eadad and phonyreal both put it best. UNC looks at everything in your application to make a decision. It's just that a lot of amazing people happen to have good test scores as well. Once you get here, it really hits you every now and then. I had interviews for UNC Fellows this past Saturday, a leadership program you apply to in your freshman year, and all the finalists were incredibly amazing people. I felt honored just to be considered of their caliber.
