I can’t speak to Miami per se, but I have sometimes run into the phenomenon of seeing the ACT scores of accepted students in one place, and the ACT scores of the entering class (i.e., those who accepted the offer of admission) in another place.
Princeton Review’s The Best 385 Colleges 2020 says the Freshman Profile ACT range for Miami is 29-32. So I’m thinking your 32 is a very competitive score for this school.
Best of luck!
