Gatorade was once a sports drink, but today it is not a sports drink - it is merely retained its marketing as a sports drink.

It may not be a super high level sport drink, and many players have moved on to other drinks (biosteel seems popular in the NHL), but it's not like nobody uses it for its intended purpose.
So just because you see athletes drinking "Gatorade" doesn't mean it's the same Gatorade that's sold in stores. It could be just water, or closer to the low-sugar original Gatorade formula with significant amounts of potassium and sodium added that the retail product lacks.
What you're doing is along the lines of "Wine, what's that? Do you mean poison grape juice??" You know what it is, stop being obnoxious.
