You need to specify your margin of error. ± the full population of humans on Earth is "a margin of error".
I may be an outlier, but I certainly remember 10+ 20-25 character random full-printable-ASCII passwords, some of which don't let a password manager handle them, others which I don't want to have in a manager. And then there's my password manager master password, which is close to 70 characters long.
And I have shitty memory—I wouldn't be able to remember what happened more than a few days ago if my life depended on it.
