I’m not sure about that. People are conflating sex and gender all the time and this looks even intentional to me just to create more confusion and potential for drama.

If you check pre-millennial definition of gender you see that it was widely used synonymously. The distinction between sex and gender is just a form of newspeak.

The current mainstream teaches that gender expression is constructed and gender typical roles are assigned at birth and by society during infancy. This is utter nonsense, has been debunked over and over again and is still based on John Moneys gender experiments with the Reimer twins.
