It's just a sample size. It's like saying "out of 100 people who own a car in New York, 20 own an electric one" and have someone say "ONLY 100 PEOPLE HAVE A CAR IN NEW YORK!" or even "THERE ARE ONLY 100 PEOPLE IN NEW YORK!". The armory is an unreliable tool for measuring the current population of the game, it's always been.
