I would have NO way of knowing this without seeing all the other applications.
But even with that, please understand that these colleges accept a VERY low percentage of applicants. Many many many well qualified applicants do not get accepted simply because there are not enough seats in the freshmen class to accommodate them all.
So…you apply and see, and hope for the best. You already have a great acceptance. So 
that some others are in the yes column as well…and are affordable.
