THis doesn’t actually appear to be true. DUS has gotten harder and harder to get into over the years as Engineering and Smeal students recognize that it’s easier to get into PSU through DUS than their intended major. The middle 50% is just that. 3.2 is way below the middle 50%.
That said, I think the OP will be just fine. But I wouldn’t tell someone with a 3.2 that they were a shoe in. I wouldn’t tell someone with a 3.6 they are either.
