Hey Ayesha,

Regarding your question, I would like to inform you that without official cut-off list of 2020 published by NTA, it's quiet impossible to make any accurate comment about the precise cut-off marks of this year's NEET UG examination. So in this case you can go through the previous year's cut-off details of several Government BDS colleges of different states through the Careers360 link given below:

After analysing this article and cut-off details provided there, I guess it's too much clear for you also that if you're a General category student it's almost impossible for you to get any kind of opportunities in any Government BDS colleges in any state with this marks and percentile. If you could manage to secure atleast 470-80 marks in NEET UG examination, then there might be some hope of getting chance in the renowned Government colleges in India.

However you can also check Careers360 college predictor tool for your own mental satisfaction in this context:
