Based on both numbers I'd have to say this is completely made up. There's no possible way this is real. I've seen those "Bill gates as the elder of zion" memes circulated around once or twice but the people who did share those are the same people who share healing crystal and astrology memes, and they're not 20% of the population.
I would have to agree. Unless they only interviewed the people who saw a targeted campaign of just that fake info, and then asked how many of them believed it. But broadly there's no way that's an accurate percentage
