You have things confused. -Water pressure cannot operate a pump. - More detail needed.
A water pump is needed to pump in fresh water.
The fuel pump basically does what the name implies. It picks up fuel in the tank and pumps it from the fuel tank through a fuel filter to the engine. The pump is set to operate at a certain pressure that is needed for the application.

Because the Earth's atmospheric pressure forces the water back down.
It provides it's own pressure. It has it's own pump which is used to create the needed pressure to wash the dishes.
There are many different ways to use a 'water pressure pump' . Any water pump will build up pressure, this is the basic principle of well pumps, and similar. Most are 'used' by a pressure switch which turns the pump on when pressure decreases to a certain point.
Water pressure makes the water run out of the faucet. This pressure is provided by the pumps in a city water system, or in the case of a home on a well, by the home pressure tank. This pressure tank is fed by the well pump and also has air pressure in it. Generally the water fills a large balloon (called a bladder) inside the tank, the pump then stops until the pressure drops (when the tank is nearly empty) In most home systems this is about 15 -20 gallons between each pump cycle.

If you mean a well tank, the water is forced in by the pump. The residual air pressure pushes the water out to the faucets.
The pressure switch is usually on the pump if it's a jet pump, or at the base of the pressure tank if a submersible pump.
hydraulic pump
Auto transmissions operate on pump pressure. The pump turns when the engine is running. This is why it leaks only when running.
