Hydrostatic Pressure: Height vs Volume

[Hepic]

Why in hydrostatic pressure we care about height and not about volume?
For example if we have into a thin and a thick tube water in the same height,why both tube have the same pressure?? Is wrong to say that the more water makes the bigger pressure? If yes,why?

Since pressure is fore divided by area, for a larger vessel, the larger weight is distributed over a larger area, for no difference in pressure.
