There is nothing wrong with being hopeful, but that does not mean that you are guarantee an interview invite either.
I was in the same spot when I thought why are they receiving interview and I dont, then I realized that stats are not enough. They might have something in their app that is more significant than you, which caught adcom's attention.
I'm not saying that you are not a well-rounded applicant, but when two applicants are put on the table, adcoms has to choose the one that seem more unique, and to certain extend, fit the school. And truth is, that may not be you.
