It is a combination of both. Oceans gain water from water that runs off from land and from precipitation that falls on them. But they also lose water due to evaporation.

Oceans can both gain and lose water. They gain water from sources like rainfall, rivers, and melting ice caps. They lose water through processes like evaporation and when water is locked into glacial ice. Overall, the balance between these inputs and outputs determines whether the oceans are gaining or losing water.
An equilibrium exist on long term.

Earths oceans gain water considering evaporation and precipitation together since when vapour is released to the atmosphere it condenses and later falls back as rainfall by about (1-5)%
Most substances lose or gain energy when their temperature changes.
The cell will not loose or gain water.An isotonic solution means that the amount of solutes outside the cell is similar or equal to the amount of solutes inside the cell. Water is moving by osmosis both in and out of the cell at equal rates; the net movement of water is zero.A cell will lose water in a hypertonic solution (more solute in the surrounding environment) and gain water in a hypotonic solution (more solute in the cellular environment). Whether or not a solution is hypertonic, hypotonic, or isotonic is relative to the environment in the cell.
