Dear Khushi, if you belong to Haryana, you should appear for All India Counselling to seek admission in Delhi Medical Colleges, Now, you haven't mentioned your Category. We do not have 2019 data yet. Neverthless, in 2018, under All India Quota, the cut offs for various Categories under AIQ have been as follows:

General Category: 612

OBC: 594

SC: 508

ST: 482

Now this is 2018 data and cut offs change every year depending on various factors such as no.of candidates appearing for the exam, no.of candidates qualified, top NEET score and difficulty of the exam. So based on your Category, you should atleast aim for 50-65 marks more.
