I'm not sure that is the case in all sports. For example in golf, the top women golfers on LPGA tour in distance are only about as long as the shortest men on PGA tour off the tee, about 290 yards average. However, the women are generally vastly more accurate than the men in pretty much every distance tee to green. Their swing is just a different style of swing afforded by female anatomy. It is more hip driven, "textbook," in fact they have higher hip speed than men who rely more on hand speed.

Now imagine a pro golfer who was born female with those anatomical advantages for golf flexibility, and is now taking testosterone for power, ostensibly to identify as male. Not only do they have the anatomy advantage, they now have the power. They would probably dominate pro golf overall, both sides of the game I expect, whichever one they choose to compete in.
