Most Linux distributions today boot to a graphical desktop environment by default. Whether that desktop environment is KDE, GNOME, Xfce, or one of the more obscure offerings, that choice is up to you. You can mix and match from different terminals too. The exceptions to this rule would be forensics distributions and a barebones secure installation that would either have a desktop environment but choose not to load it or it might not be installed at all.
By default most linux distributions give you a single display assuming that you have a computer or laptop with just one physical display device. But there’s no reason you can’t take advantage of multiple sessions using your virtual terminals instead of just 1 gui with a bunch of text consoles.
