It's an analogy, and all analogies are imperfect. Using the speed of water moving is a good description for volts in an active electrical circuit, using your example of potential energy is a good description of a resting battery.

In this discussion we were describing the former not the latter.

Amps relates only to the "amount" in a single moment, not the amount over time.
