Evaporation, condensation, precipitation are all part of the water cycle. After the precipitation, the “destiny” of the water is ground water or surface runoff.
Groundwater is the term for all the waters beneath Earth’s surface, that fills in porous spaces in soil, sediment, and rocks. But, when falling rain cannot be absorbed by soil (saturated by water) and become groundwater, it flows over the surface and this is called surface runoff.
