the type of maths my man here is saying is along the lines of saying (the average) men are taller than (the average) women, very much true, and there's signal there and there's genetics that make men on average taller... but that's nothing to say that if you pull a random man and a random woman off the street - there's no guarantee the man will be taller.

Whatever genetic signal and influence is found between groups A and groups B, A and B are so highly variable within themselves that none of this is applicable to comparing individuals beyond a perhaps slightly weighed dice.

Your first paragraph is obvious. Your second paragraph is not generally true. Neither have anything to do with what I said.
