Sorry, no, that is not a fact. It's a myth best filed in the same trashbin as "Breaker points are better than electronic ignition!" and "Carburetors are better than fuel injection!" and "Bias-ply tires are better than radials!" and "Leaded gasoline was better!": fun to think about in an old-car fantasy-world kind of way, but not a part of reality.
You don't have to believe me, and you don't have to correct your basic misunderstandings of the matter if you don't want to; if you dig back through old magazines (everything from car mags to Popular Mechanics/Popular Science/Mechanix Illustrated to Consumer Reports) from when disc brakes were becoming widely available as an option, you'll find a lot of "Should your next car have disc brakes?" types of articles where they test a car with drums and the same car with discs. You might find the odd case (an unusually good drum system vs. an unusually poor disc system, that kind of thing) but the overall result is very consistent and it runs in one direction only: the discs are better from the first stop on.
And that's on cars carefully inspected and adjusted exactly just right to make a "fair" comparison. If we ask the question in terms of the real world where drum brakes are usually at least a little out of whack, the discs win even bigger.
