There are no heists in Heat?

I search for movies like Inside Man and posts recommended Heat.

But there's pretty much just 2 robberies? In the bank scene, they wear masks but have their faces seen before they even put them on and just open the safe.

Reviews also mention this as a heist movie.

Is there a distinction between heist and robbery? I thought heists were like complex thefts that the people didn't even know that the money is gone
