Admission rates are heavily dependent on how easy it is to apply, how many times you're allowed to apply, how likely a student thinks their chances are, basically heavily dependent on the college application process, which is very different in different countries. E.g, I think Indian IITs have <1% acceptance rates but you probably don't have to shell over a $100 to apply.
