No one is going to have all that information about another person unless that is a family member, and even so sharing them would be just creepy. In any case that is not going to help you more than looking at NYU’s officially published statistics which is in @happy1 's link. You could also scroll through old accepted students threads from NYU, but you are not going to get reliable or useful secondhand information otherwise.

Don’t spend as much time comparing yourself to others, and spend more time maximizing your own chances.
