Speaking as someone who tried to take a tap class as an adult, only to discover it was for people who were already experienced dancers: yes, dance training is vastly more complex than exercise.
Update: what absolutely killed me is that we would run through a complex step two or three times, and we were expected to be able to practice at home. I didn't understand what we were doing while we were doing it, there was no way I could reproduce it.
