The first claim is that less women are competing because it has been invented by men for men (and only a long time after were women allowed to compete)

which is not contradictory nor opposite to claim 2 that the level of women would increase if there were more women competing.

Look at pro cycling. 25 years ago I was riding in circle around an elite women cyclist as a junior. Now they haven't reached the same level as I had and are still far away from elite men (who are also much more to compete) but they are much closer because there is more money to the sport, more women competing. Now if races were 5to 10 times longer the difference would probably be lower as found in ultracycling events.
