Yes. As much as 90% of the water used today was usable water thousands of years ago, as it goes through the water cycle. There is ground filtration, and the flow to the rivers, lakes, and oceans, and evaporation at every stage that is not underground. This water returns as precipitation. Living things hold water, but this is returned when they die.
There has been some water lost to hydration of rock, to chemical combinations, and photodissociation into hydrogen and oxygen. There has been some water exchanged, as in the snow and ice that gets locked in ice caps while older water is released from glaciers and icebergs. Some new water has come from lava eruptions, and a comparatively tiny amount from meteors.
