Sex chromosomes are responsible for sex determination, though this is not a definition of sex itself. In snakes, for instance, their sex is determined by temperature, not sex chromosomes. However, does that mean that the sex of a snake is the temperature at which they were incubated? Of course not; this distinction is straightforward. In other words, although there can be multiple variants of sex chromosomes, they determine each individual to be one of two sexes, both sexes (hermaphroditism), or indeterminate. In other words, sex is fundamentally binary.
Have you carefully evaluated what you've read? What does a "traditional male" even mean? What would a "non-traditional male" be like? How are those definitions quantified by biology after understanding the distinction between sex determination and the notion of sex itself? This is frankly just language games and newspeak.
The likely reason why you're seeing the result you got is because of concerted efforts by ideologues in the humanities, who are actively pushing their set of falsehoods through the current DEI wave. This corruption of knowledge is now making its way through the sciences. Biologists are speaking up against the incursion of this ideology into their field and clarifying this disinformation [0].
P.S. I've added an additional source [1] that directly disputes your source. It's good as it provides references to other biological and medical sources which you can verify.
