>Does that mean the learning was in vain? I’ve probably forgotten 90% of what I learned in high school other than math. Does that mean most of my education was a waste of time?

Did the things you learn change you in some other fundamental way, that only learning those things could (ie you could come to a conclusion and forget the exact process that brought you to that conclusion, and thus the process was worth learning even though now forgotten)?

If not, then that learning must have been in vain, almost per the definition of vain, right?
