We always see all these ornate and very old fountains around France and Italy. I want to know how they made them work without electricity. Where did all that water pressure come from?

Old water systems were gravity powered. Water came into the city in aqueducts, from the hills, and was stored in elevated cisterns. This elevated storage provided the pressure to run water through the pipes and to spray it into the air in fountains.

Are you asking if a water pump can work without the presence of water anywhere? Or are you asking if a water pump can work without any water in it? If the question is the latter, the answer is yes. Some pumps are what they call self priming, which means they can pull the water up to then even when they start out dry or primarily dry. I guess that if you think about it, a water pump can work with other materials such as molasses or syrup so that they can operate without the presence of water as well.

All they had was gravity so that is what they used. After the water towers in your city are filled by electrical pumps then the distribution to customers is by gravity so that is still useful.
In Massachusetts most of the drinking water in Boston gets there (except for some recent booster pumps) using gravity from the reservoirs in the hills of the western part of the state.

They did this by the pressure caused when supplying water through conduits or underground aqueducts .

I think they made the little boy statues drink a lot of water.
