There is no such consensus. Scientifically, “sex” is so much more complicated. Hormones, hormone receptors, gonads, genitalia, secondary sex characteristics, and reproductive gametes, to name just a few of the components of biological sex.
People who are biologically known to be inter-sex (never mind anything about gender or identity) outnumber those with natural red hair.
But all of this is relatively unimportant. Only a doctor would ever need to know most of these things about a person, and only a doctor or a potential sexual partner would need to know the others. There’s no circumstance in which anyone else needs to know any of these details about a person in order to decide how their interactions with that person should go. Especially not anyone who doesn’t have a close personal relationship with the person. Gender is how someone expresses themselves in society, and that’s the only thing that matters in most circumstances.

Sex is defined by gamete size. You’re confusing sex with phenotype/genotype. Intersex people still produce one of two gamete sizes
