"Also, my parents think it is really easy to get a full-ride "
your parents are using “magical thinking” to avoid the reality of how much it really does cost to go to college these days.
It is NOT easy to get a FULL RIDE, which means free tuition, room and board, +books. They are rare and offered only to tip top students- i.e ACT scores of 35-35 and 4.0 GPA’s
There ARE colleges where you can get full tuition scholarships. Any additional costs will probably have to be paid for by them and you . Loans can cover some of the costs.
