Hi,

Well all india quota counseling for 50% all India quota seats is for all the students who qualify neet exam and can sit in the counseling. Remaining 50% state quota seat counseling by state quota body is only for state domicile students who belong to that particular state. State quota usually have high chances of getting a seat but at the same time all the college's don't fall under state quota.

I hope my answer helps.

All the best.
