Is the pressure of a liquid a phenomenon or a property of bodies, of a substance that characterizes a given value?

There is pressure in any liquid. At the same time, the pressure is different in different liquids. This is due to the fact that pressure depends on the density of a particular liquid and the height of the liquid column. Pressure is measured in kilo-pascals, which corresponds to the mass in kilograms acting on an area of one square centimeter. With an increase in the liquid column, the pressure increases. It is for this reason that a person cannot (without special protection) withstand the pressure in water at great depths in the sea or ocean.
