Am I spoiled? Cause I don't think I am that spoiled. I'm 18 years old?

If you are able to have nice things, go you. It seems like you do donate some to charity. All I can say is that I hope it was your own money and not your parents. Spoiled is a lot about attitude. If you're acting like a brat that thinks they are above others because of their financial status and never does anything to help someone else, then that person is spoiled. If your parents have taught you the value of a dollar, even while being able to afford nice things, then kudos to them and to you for having a good attitude.
