Yes in the sense that it gives you a mouse/keyboard windowed experience instead of a touch-optimized one with a mouse cursor.
You also still get to use the phone/tablet at the same time while it's driving the desktop.
Of course you're still using Android apps, just inside of resizable, movable windows, and not all apps behave well or work as well with mouse/keyboard as you might like.
But you can install linux shells, remote desktop apps, etc, and basically just use it as a thin-client.
There's also a way you can use Dex inside of a window on Windows and it let you drive your phone without actually touching it or doing some weird remote access stuff to your phone.
Dex is kind of a hidden gem of the Samsung devices. Once you hook up a dock with some I/O it's basically just turns your Android device into a desktop computer.
