Good question. Actuarial Science is actually a minor at UMiami, UCF, UF. Actuarial Science is really a Math Major at most universities, and involve nothing special, but a series (handful) of advance math/statistics courses. One can get a good Actuarial Science preparation at any of the FL 4-year universities. FSU might offer the best Actuarial Science program in the State.
The OP is from Florida. I guess the OP is just a casualty of the high cost of NYU, since it was clear NYU was known to be a very expensive institution going in. UMiami Tuition is about $43K/yr, while NYU is about $47K. Room and Board cost would be less, especially if the OP commute or live off campus. Very difficult to get off-campus housing within walking distance of the school. Many students have to drive 15+ minutes to get to campus.
