Of course. No one literally thinks that “dude” always means man.
The issue isn’t the obvious truth of the different meanings. The issue is that those different meanings aren’t neutral like they claim to be, because they rely on the idea of men being the “default” state of people.
There’s a reason there isn’t exactly a large number of words in use that can men “woman” and “everybody” and that’s because most men would be uncomfortable with that.
