Hi Raman,

AIIMS UG 2019 results have been released on 12th June, 2019. They have released the list of qualifying candidates and cutoff percentage. If some of the candidates in the merit list do not take admission in the college, then the subsequent candidates who have qualified but are not in the merit list, will get a chance to take admission. So, as asked by you, such people may get a chance to be a part of the following rounds of counselling procedure.

Hope things are clear now. 

Feel free to ask other queries here.

Good luck!
