Wayland has a thing called Xwayland. Which is an X11 session running within Wayland to ensure X11 apps can function within wayland. You can remove this if you want to (though X11 apps won't function).

However, Wayland as a whole is a seperate thing. It's basically a set of protocols, a Wayland session is a session that is built to be compatible with said protocols.

So both are different things, but you can run most X11 apps within Wayland if you choose.
