Heyy raghav
Assuming that you belong to general category With 584 marks I think you might get govt medical college through all india quota. However i am not sure whether you will surely get or not but at least you can try. It also depends on which state you prefer. States like Rajasthan delhi and kerala have high cut off as compared to other states.
We are predicting this on the basis of previous year cut off trends. We. Are not sure about this year cut off as it changes every year depending on no.of candidates, no.of seats and difficulty of exam. So hope for better result this time.
Here is a tool which can predict college on the basis of neet score. I hope this might help you

Hello, though you have a very good score but your admission will depend on which college you apply for and what category you have, if you belong to reserve category you have chances for getting admission in well reputed government college under AIQ also, being in general category will raise your competition a bit higher and you may struggle getting through your desired college.
Hope for the best though,
All the best,
Thank you.
