the dinosaurs lived from 250 million years ago to 65 million years ago.
Well, for starters, dinosaurs first came to the earth around 280 million years ago, they were wiped of the face of the earth around 65 million years ago. Technically speaking, they have lived for a total of 215 million yeas ago.
the total amount is 98%
Any freshwater on Earth is usable
yes
Roughly 97% of the total amount of water on Earth is salt water found in oceans and seas.
In all likelihood, probably. The water cycle would make sure that all the water on the Earth would be used, evaporated, and then sent down into the Earth over time. The amounts of water may have changed slightly over time, but the relative amount of water hasn't changed much at all, just the water placement and it's distribution.

The total amount of water on Earth is distributed among various reservoirs such as oceans, ice caps and glaciers, groundwater, lakes, and rivers. The majority of Earth's water, about 97%, is found in the oceans.
If I have understood the question correctly, the answer is yes.
The total amount of water on Earth remains relatively constant because water undergoes the hydrological cycle, where it is continually recycled through processes like evaporation, condensation, and precipitation. While water may change states or locations, the total amount of water on Earth overall remains the same.
