He is incorrect because only about 1% (actually much less than 2%) of Earth's water is immediately available to drink.

Why: about 97% of Earth’s water is salt water in the oceans. Only ~2.5% is freshwater, and most of that (~68–70%) is locked in glaciers and ice caps and another ~30% is groundwater. Only a tiny fraction of the total (surface water in lakes, rivers, swamps and shallow groundwater) is readily accessible for human use — on the order of about 1% or less of all the water on Earth.
