Obviously they do give admission to the waiting list students. When any student leaves the seat then the students in the waiting list are asked to take admission and if the first one doesn't take admission then its given to the second one and if the second one also doesn't take admission then the admission getting option is gave to the third one and the process goes one.

So you may have a chance to get in PU once a student leaves the seat. So just wait and lets hope for the best.

I hope my answer helps you. All the very best for your future endeavors!
