Exceedingly rare.

Yep, the usual rules about sex (male|female) which would likely be XY vs XX and genitals/sex organs would not exactly apply to the rare exceptions listed above. But for everyone else, I think genetics and the sex organs that you were born with should rule the day.

Of course the big thing these days is that sex != gender.
