Do I need to worry about AP if the school I am going to didn’t offer any AP or offer only a few AP?

Actually, I think it depends on where you are likely to focus your college search. If you are thinking mainly of East Coast schools, the lack of AP tests won’t matter. But if you are planning on prestigious universities elsewhere, including privates like Vanderbilt/Duke/Rice or publics like U. Michigan, UVA, UCLA, U. Florida, etc., I think it would hurt your chances.
