With all due respect, you didn't "learn" these languages. You got a superficial understanding of these languages. It's like someone who learns to say "hello, name is John, what is your name" in 17 human languages saying they learned 17 languages.

Being able to write "hello world" in all these languages doesn't mean you "learned" it.
