Admittedly, the stats are not fully consistent. This is due to the fact that it's hard to conclude on actual human users based on the amount of wallets. I've seen reports saying 1 in 6, 11%, and there's this report:

...which states 22% of US adults. If you select for a somewhat younger population (non-boomers), it's even 33%.

So I think the point stands, whether you pick the lowest or highest number amidst these studies. Bitcoin/crypto is far more widespread than some people think.
