Hello Aspirant

Based on the past few years cut off data the SC rank that you secured is indeed a good one and very much useful to get you a seat in your desired institute. Next comes the admission possibility determining factors such as

The number of students who appeared in the exam,

The difficulty level of the exam

The vacancy matrix of the colleges

But it is an interesting fact that with 1000 SC rank you can get your preferable college but the stream which you choose matters.

Hope it helps!!!
