Greetings to you,

As per your rank in JEE Advanced 2019, I am sorry to put this infront of you that you cannot get any seat in any of the IITs. A ST candidate must secure atleast a rank within 900 (ST category rank) to stand a chance for a seat into IITs. But you can apply for private institutions or state colleges that accept JEE Mains score/rank for admission or those who conduct their separate admission tests. Good luck. 

Hey!There

Seeing your score ad previous year cuttoff of Jee advance,you seems to have less chance of getting seat in IITs through ST quota.You need  St rank under 800 for IITs.You seems to have less chance Chance.

Ask if you have any other query.

GOOD LUCK!
