Basic biology is basic for a reason: to teach children. Yeah, the only two combinations of sex chromosomes are XX and XY and gender doesn’t exist because we just assign groups based on the most common phenotypes. This works very well until it doesn’t.
In practise there isn’t even that solid of a connection between XX/XY and their respective associated expressions.
Cell development is highly influenced by the hormones that are present. This is especially true for sex-related cell development. This is why intersex people exist. Your genetic code just provides a bias for specific hormone production, which turns into a self-regulating loop once your cells develop into organs which produce more of their respective hormones. This is also the reason HRT is an uphill battle, and some trans people choose to have their ovaries or testicles removed.
Even biologically, the concept of biological sex makes no sense.
I agree with this meme.

The next part of the meme should be:
There’s a fair few more than just XX and XY
