Kind of a complicated question, but not necessarily, gender (or sex I guess) does impact ability in many sports. I say complicated because it's not just about the number of people employed, but also how much they're paid, whether or not there are separate leagues, what about the coaching staff, etc. It's fine to think of pro sports as one of the very few professions where you're performing so close to the human limit that biology actually becomes a factor. It's not just gender, for example short people won't be equally represented in many sports, which does not need to be true for almost any other job.
