You are using a source that literally says "we don't have enough information to come to a conclusion, but here's what we do have" and presenting it as fact because you agree with it. I would call your understanding quite unreliable.
What we do have enough information on is the differences between the male and female body. Studied for centuries. There are significant differences between the two that lend themselves to physical advantages. Pretending biological males are not at a physical advantage over females is absurd and not based in any kind of science or reality.
