This might be true if the Olympics were exclusively classifying the 23rd chromosomes, and nothing but.
Leave aside the fact that very few of us here have actually tested our 23rd chromosome. Historically, the Olympics have not been (and are not) strictly chromosomal. The 2023 testosterone suppression decision requirements has exclusively impacted cis women, for one example.
Humans are biologically dimorphic in the same way winters are usually cold and summers are usually hot.
I would say that humans are sexually dimorphic in the same way that humans are bipeds. if you attempted to make a serious argument that limb agenesis implies that we’re a variable-limbed species it would be obfuscating rather than illuminating.

When people do submit to such testing, how commonly are the results other than they expected?
