You really think that's not a small number of sports? The Summer Olympics currently have 28 different sports and the Winter Olympics has 7. And there are many sports that are not included in the games.

Also, I'd defy even most elite men to be able to beat Serena Williams at the height of her career. She's starting to lose her edge now, as inevitably happens with age.

Katie Ledecky beats men in training so regularly they won't swim with her any more.

Okay, so these are outliers and have put in a lot of work and effort to get where they are.
