Hello, Ayushi 

Congratulations you have secured a good score. But it will be difficult for me to say that you will definitely get a government college as cut is different every year depending on category home state difficulty level etc 

However 507 is a good score and also you are OBC. You have a good chance of securing a seat in government college

I'm providing you a link which can help you more
