What state do you live in?
If you aren’t on the east coast, and your parents aren’t tapped into the current college rumor mill, then it is entirely possible that your parents have never heard of the places on your list. It also is likely that they don’t understand how difficult it is to be admitted to an Ivy these days.
So, have a chat with them about how much they can pay for college, and find out what places they’d like you to apply to as a back-up for their current all-Ivy list.
