Your marks as per your state rank will obviously be 500+ but you might be knowing this year the cutoffs are expected to rise since the number of candidates had increased and also the paper level was called easy comparatively. Moreover, students from Rajasthan have performed exceptionally well as analyzed by the students, so the cutoffs will be high in your state. Every college will have cutoff around 570 this year and above whose equivalent rank will be around 1600-1700. So you seem to just fail to achieve a GMC in Rajasthan. You can think of a repeat if you so willing to do MBBS only from a GMC. You can try for private medical or dental colleges as well.

Best wishes to you brother. Thank you.
