you'd get a similar amount of randomness with a lens cap over the camera; it's a neat gimmick, but still a gimmick

This is correct.
The goal isn't to capture all of the randomness of the water but instead to capture enough noise to produce a seed. All of the changes in the room get averaged into a pixel. The water just makes the room change more.
An interesting question I would have is do you get just as much randomness without the fluid at all?
