I have scored 464 in NEET UG 2019 With AIR-73128 and Category Rank-2828 Can I get seat in delhi?

Hey Manish !
In order to answer your question, we would need to dive into the stats of previous year in order to gain some idea about the Delhi Counselling.
For the AIQ SC students, the closing rank for Delhi stood at 18,654 which is practically quite far from your rank.
Now, let's look at the DU Quota, the closing rank for the same was 65,197 which is actually too close to your rank of 73,128 although your chances are less.
But you do have a very slight chance of getting in.
