That was my hunch as well. People who don't care about learning topics deeply. Understanding why something works etc.

I noticed that a lot in school/work. People can get good grades even without understanding the topic at hand. Many learn mechanistically and succeed with good grades.

I do the opposite, but it takes time and effort to learn a topic deeply using the Feynman method. Many are not interested in this. Many just apply formulas and code snippets, and they succeed nevertheless. Good for them!

I actually don't care about success or grades or whatever. I care about the topic, because I want to understand why it works. This is just me though. ¯\_(ツ)_/¯
