Is KDE Plasma X11 or Wayland?

This is a super noob question, I loaded the iso onto a USB and booted into it, never got to install it yet as my 3 drives are all being used for some purpose

I messed around with the live instance and when I went to system information I saw it's running X11, again I don't really know what a lot of this means yet but I thought CachyOS was running Wayland? Do I have to switch desktop environments to run Wayland?
