It's not that clear-cut as cis women with abnormally high testosterone levels are overrepresented in top level sports, to the point where competitions that tried to define the men's and women's groups based on testosterone levels end up with cis people on the wrong side of the line. Also, hrt for trans people is usually stronger than the natural hormone levels of a cis person of the same gender as it's meant to change their body rather than just maintain it, so the attributes that are more dependent on hormones typically overshoot.
