Screens crack because they become weak around the points at which they scratch, so if there are no scratches on the screen, there are no weak points on the screen for it to break along. They just make sure that pressure gets uniformly distributed along the glass so that it has less chance to break. That is the main functions of screen protectors: eliminating weak points on the screen.

I guess it has to be a pretty deep scratch relative to screen thickness, to have any substantial effect.

Actually, the scratch doesn't need to be that deep to have an effect. It's the way that crack resistant glass is designed.
