Where the hell are you getting that from?
Having a kid that had gone through this college process - I learned quickly that if you have some things that are different than the average student make up - you can get more scholarship money and be selected at a school where your grades are just a little below the average.
My daughter got into a highly selective school with a good scholarship and at the last minute they threw in some more money to try to entice her - I honestly believe because she was a good softball player. It was division 3 so they cannot give you money for athletics, but they can give it for almost anything else - it can be so gray you really do not know how you got that scholarship. She was a good student in high school - but was not a highly selective student academically. Her guidance counselor said it was a stretch school for her - meaning might not get in.
She ended up going elsewhere that she felt fit her overall better. They also gave her a good amount of money - not as much as the other school but this school was less money overall. Anyway this school she got a leadership scholarship. They use these sorts to get a more diverse student body - which can mean students of color, sexual preference, ethnic background, they play the flute, you are from New England, you are overseas, you have blue hair - pretty much whatever they are trying to accomplish.
A female from New England studying in the sciences, plays sports - are some things that made her stand out (or at least I suspect) and give her a leg up at a small private school in Virginia - most of the kinds are from Virginia and other states around that area. Now her grades were right in line with what is considered "selective" - not highly selective - so she was able to snag a good scholarship overall.
The schools do not hide this - they do say they look at a variety of things when choosing students not just grades.
However, when you get into the very high academic schools - you do need the grades - but it is so competitive to get in, that you can still have the grades and not get in - so it helps to have some sort of something that helps build the schools diversity for what that they are looking for.
