Hence, being an extremely sexually successful male is much more rewarding for the propagation of their genes than being an extremely sexually successful female.
Thus, males evolved to take more risks than females since there is a much bigger payoff for them: if a male can become an "omnipotent king" he can father children with every woman and spread his genes a lot, while a female "omnipotent queen" still can only make one child for every nine months.
Hence, males have more variance, meaning that the top in any field are very likely to be males, but also there are going to be much more men who are extremely unsuccessful.
This also means that women are probably better off on average, since psychological (as opposed to genetic-propagation-related) utility is logarithmic and thus reducing variance is advantageous for the individual.
