CMV: Saying that the world is "97% water" is wholly inaccurate due to the false equivalence of ocean salt and freshwater

Major edit: I finally had the chance to speak with a real oceanography expert on this issue, and it turns out that I was mostly incorrect. The term "brackish" is often used to describe combined salt and freshwater. That is essentially what nearly all water on this planet is. The term "97% saltwater" is descriptive of the brackish waters we have, as opposed to freshwater, which is *not* potable. That percentage of "saltwater" is an accurate way to describe our water supply. Thanks to those other comments that were helpful as well.<br><br>TL;DR: Essentially the entire ocean is made of saltwater. But if you combine salt with freshwater, they are not equivalent in the sense of potable vs. nonpotable water. So when we say 97% saltwater, that percentage is descriptive of water that contains salt, which cannot be consumed, and is vastly misleading. So the 97% statistic is not an accurate description of Earth's water.
