Is it true that hydrostatic equilibrium is calculated by balancing the downward force of gravity with the upward pressure gradient force?

Hydrostatic equilibrium is a fundamental physics and astrophysics principle describing the balance between inward gravitational force and outward pressure gradient force, and no citation is needed for this basic definition.
