The Gators turned up their backcourt pressure to narrow a 10-point deficit to 51-48 with 2 minutes left on two free throws by center Patric Young. Another free throw by Young cut it to 56-53 with 41.8 seconds left.
But Jackson hit a floater at the foul line over Jacob Kurtz with about 10 seconds left and Frank Kaminsky blocked a shot on the other to seal the win for Wisconsin (2-0).
Michael Frazier II led Florida (1-1) with 20 points.
Dekker's 3-pointer with 11:06 left in the first half sparked a 22-10 run for Wisconsin.
