Go through this article and you will know what does a percentile mean.

Hii

The percentile score is calculated as follows-
100 * no. of candidates appeared in the 'session' with raw score equal to or less than the candidate / Total no. of candidates appeared in the session .

So if you have scored 92.723043914 percentile, this means you have scored better than 92% students those who appeared in you shift and that only 8% of students of your shift have scored marks higher than your marks.

I would like to congratulate on your success. You have done a great job and scored a decent percentile.
You have a high chance of being eligible for JEE Advance and also for admissions in NITs.
But yes this is not guaranteed as the cutoffs are yet to be declared.
Incase of anymore help feel free to revert back.

Hope this helps
Thanks!!!
