water that falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. When it ends up on land, it will either soak into the earth and become part of the "ground water" that plants and animals use to drink, or it may run over the soil and collect in the oceans, lakes or rivers.

Hi
A negligible percentage, significantly less than 1%. Rivers occur only of the surface of the earth, around 70% of which is oceans. Rivers occupy a tine proportion of the remaining surface. Compared to the radius of the earth their depth is negligible so that they occupy a minuscule proportion of the earth's volume.
