It really depends.

It really depends.
If you are in a display driver, and according to reported capability
and system configuration, you may have a call to one of those
WDDM - DxgkDdiSetPointerPosition
XPDM -  DrvMovePointer / DrvSetPointerShape.
In any other environment, the information is not accessible.

I dont understand: Why do people need the position of themouse on the screen

I dont understand: Why do people need the position of the
mouse on the screen inside a driver??? This is something
that you will need in user mode with user interfaces not
inside a driver. If you want to restrict/set the pointer to
something or somewhere, then you simply write a user
mode app and leave that task to it,...

How does this work, is not the cursor position a session thing?

How does this work, is not the cursor position a session thing? What cursor
position would I get with that method? I must confess I know nothing about
the relation between the video driver and RDP, but my psychic powers tell me
that there is none.

Thanks,

XPDM display drivers are Session-Space drivers.

XPDM display drivers are Session-Space drivers.
Only the XPDM miniport is a System-Space driver, but,
that is not cursor aware by any standardized means.

For WDDM, only the session bound to the glass terminal
can use the WDDM stack to drive a primary attached to the desktop,
so the problem is somewhat solved, because you can draw
a cursor only to a scanout surface.
