We were a class of 6-8 students, in pairs making our guesses of what the words that we didn't "understand" meant. We all got pretty advanced ideas and all got to similar conclusions. The teacher would tell us afterwards how those were made up words, and we were all in awe at how much we still understood and agreed upon the meaning of the words.

Sidequestion, is this poem taught in schools in the US by any chance?
I have no clue what a "N2" is and I'm not entirely sure what you meant by "Kanji/readings". There are only six other sentences of context and they didn't really help to understand the first one.
Kanji: The Chinese characters in question
N2: The second highest level of the Japanese Language Proficiency Test (JLPT). N1 is by many seen as a very high bar and many Japanese employers demand it if you'll be using Japanese as your main working language. N2 is generally attained after 1-2 years of Japanese studies.
Ideographic, as in trying to portray ideas graphically, not idiomatic, as in using expressions like a native speaker
From my own experience, this would only be true in the most favorable of the situations. 2 years studying fulltime while living in Japan sounds about right. 1 year studying as a hobby few hours a week, no way.
For context, it took me 3 years of university (outside Japan) to pass N2.

(I'm just amused of all the % thrown around I this thread)
This is a dangerous and corrosive mindset that did a lot of harm to me and other people I know. It took me maybe until 25 to actually start to accept my lack of knowledge and incompetence and start to do something with it. I sometimes wonder what my life would be like if I had the emotional maturity to challenge myself at a young age instead of pursuing destructive perfectionism.
From a quick Google I gathered that there are 5 levels of proficiency you can certify with. They are N1 to N5, N1 is the highest rating.
Maybe whether one can make a reasonable guess depends on more than the context - perhaps background, experience, and point of view. I know I've missed points that are obvious to others because of our differing perspectives.
And allow me to claim that you've actually proved your parent's point! I have no idea what an "N2" is either but from the context was able to accurately guess that it's some kind of proficiency test.
I also read/type Japanese (my writing out of lack of continuing to write on a daily basis has gone to the dogs). With four years in Japanese universities and 20 years living in Japan I had the opportunity to experience what it is to get reasonably proficient in a second language.
The synaptic connections you can make by understanding 'most' of a compound kanji (multiple characters joined together) along with parts of the kanji makeup for a specific kanji you do not know puts you in an incredible position to figure out what the word is likely to mean.
Regardless, once you Japanese gets to a point, you begin to realise it is less about the meaning of words and more about the context and usage of language. You find yourself understanding how to use some words you have not studied without having said to yourself 'so what is this word equivalent in English' - and at times there is not a word equivalent in English. That is when you realise you are thinking in Japanese not just translating.
Synaptic connections, context and knowing what the relevant responses to how you want to respond are the key to fluency in my opinion. This is also the case for writing emails etc.
This also explains why people who do homestays where they get to watch people interact with each other progress faster than someone who goes to live with their significant other half. If you are involved in half of the interactions you get less opportunity to mimic the common responses.
Sorry for digressing a little on this one. Once you get that 777 kanji mark you would be well on your way to being able to contextually understand much more for the kanji/sentences you do not fully comprehend - which in turn leads to more kanji being 'gut-felt' understood if not fully formally learnt.
An additional benefit once you get some proficiency is that you can hear a word you do not know - but you can guess the half of the kanji being used in the compound word (and confirm by asking) and that gives you some context of what the word means. Very much like using latin/greek roots in English to breakdown words.
Time to go back to my coding before the day gets away from me. I just needed to respond to this one because I thought Diego's opinion on language learning was too far off the mark from my experience with it.
Funny as this is how I learned (and have similarly described) to read language X and it felt ___almost___ like zero resistance. I learned first just to identify each character by name, then somewhat how they were pronounced, then vowels, then how there were pronounced, then special rules for X, then special rules for Y.
All of the learning material clump them together from start, a few consonants, a few vowels, some of their properties, and rules on how to combine them. All at once, this made me ignore writing for years until I tried it my way which I think worked well (although it took some time, still).
If I hear something that amounts to "you idiot, get the schmonck out of my way", I'll understand even if I have no idea what "schmonck" really is.
Sure, reading isolated sentences with only 90% coverage is really hard sometimes. But usually you're reading whole blocks of text, so you have context. Also, maybe you don't know some kanji but it has similar radicals to other, so you can make educated guesses (only sometimes of course).
I mean it's just like English! There are radicals/etymological clues, there are context clues, there's so much that you can work off of to figure things out. And exercising "figuring things out with partial information" is a valuable skill that can compensate for a lot of missing kanji knowledge.
An aside: I've heard that when learning a language, you should be able to understand roughly 80% of what you're reading/listening to, because then you'll have enough of a base to not feel overwhelmed, while still having new stuff to absorb.
