Hello Pratik Kashyap !

RIMS is one of the best colleges to offer the medical course in Ranchi and many students iam for that.

You have good chances of getting admission in the 2nd round of state counselling.
For example, in 2017 the state cut-off rank was 114 (UR) in Round-1 which went a little higher in the consecutive rounds.
The cut-off has been increasing every year because of increasing number of students applying for it. Although, you have obtained a good rank and have nice chances of admission here.
You can use the below link to get the previous year's college-wise cut-off ranks in Jharkhand medical colleges-
