Help regarding available options

I, 18F, have got 2,75,000 CRL in jee mains 2026. And i am confused reegarding the branch i would be getting.

My preference is IT or CSE/CSE specialisaiton branches, and it would be highly helpful if seniors could guide me whether its possible or not with my rank, considering even seats have increased since JIIT is provate, i dont think any quotas are there either.

Spot rounds i realised are heavily luck based, i may be wrong, idk much. So if possible, help me based on stats where branch allotment/upgradation occurs in counselling rounds online, and not the spot rounds.

And for the last resort, what are the odds of me getting what i deisre in spot rounds.

But kindly ell me first about my chances before spot round.
