No, I don't really see the two scenarios being the same. I agree that my kid flunking out of school would not be made any better by another kid not getting a scholarship.
A rivalry in sports is a different situation. I don't want the Astros to win either, but if they are eliminated, that doesn't really help in getting over the Red Sox season. When there's a motto of "Anyone but the Yankees", however, the Yankees being eliminated is big.
