Kids who get the big scholarships are generally the really “pointy” applicants (ie: not “well rounded”, really amazing at one or two things). They’re people where they adcoms can look at their application and know exactly what this person is all about. They have well developed and obvious passions and have achievements in the one or two things they are into. Some have sky high stats and some don’t.
But I wouldn’t think about it too much, it can be somewhat of a crapshoot. Worry about it if you get an offer later on.
