If you ask a biologist, you will find that categories like "woman" are not clearly defined. Even the concept of biological sex is really complicated. If you want to pretend that this stuff is all black and white, that's up to you but its not a scientifically literate perspective.

That's not the same as saying that "everything is defined by society/culture?" That's a strawman - no-one was claiming that.

In some insect, reptile or fish, like the clown fish, sure.

In mammals? It’s not. And to be more specific, in primates, it’s not.
