hello,

No it won't happen like that. If you apply for any college which is in the state where you live then only you can use home state quota which is also known as domicile reservation which is kept in every college it may be private or government.

If you apply for any college out of your state then you will go under open category and you have to satisfy the rank cutoff in the open cutoff category of the respective college.

If you want to get  selected in any college in your state then you have go through the process and use the state quota else you don't have to. you won't loose anything.

Hope it helps!
