how knowledgeable are you on different genders and sexes?

this is so so embarrassing, but i did not know the difference until i read this thread: https://www.mangago.me/thing/about/578043/. ive known for a while that i should educate myself on this type of stuff but ive only read a few articles on nonbinary pple so i feel a bit ashamed of myself. no very ashamed-
anyway.. have you guys made sure to educate yourself on abt different genders and sexes? have you had someone to educate you about this stuff or did you have to use google bc you were curious yourself? it was v obviously the latter for me.
