Wayland is a more modern display protocol, but some older programs don't work on it.
I have a package installed called xwayland which "provides an X server running on top of wayland". Does that mean I'm running both, sort of? I'm running Gnome on Stretch and gparted works fine, and I'm logged in with the default Gnome session.
You are running the X session. If you log on with Gnome with Wayland then gparted will no longer work. You can always verify this by looking at the output of top. If X is started then you are on X, if xwayland is in the list, you are on Wayland. The few x apps that require privileges will not run on xwayland at all (gparted, synaptic package manager )
