Also, definitions of words can change. Humanity is adopting "gender" to more specifically refer to gender identity expression, because it was some oonga boongas who decided, for no concise reason or with no consistency, that people with penises and vaginas should wear different clothing.
Also, we use "sex" all the time in scientific spaces. You "sex" an animal to find out what genitals it has, and they engage in "sexual/asexual reproduction". Those are also common in children's educational media like nature documentaries.
