Yes, dragging your finger on the screen is analog to moving the mouse with no buttons pressed: only the cursor moves.
It works like the trackpad works on a laptop. You need to double-tap and hold. (like if you were double clicking), but hold the second tap. you can then drag your finger, and the cursor will move with the primary button pressed.
This can be used for drawing, but also for dragging and dropping, or selecting.
Hope this helps!,
