"350" ...

well, then we play password games in different leagues

I have 8 main accounts (2 banks, 4 emails, 2 other) and those I remember. In addition there are the cryptocurrency accounts, whose passwords I do not remember, not always.)
Those usernames and passwords are in at least 2 safe places, not meaning digital stores.
Other different accounts, ~ 20, are not so important.
All the passwords, which can be in the computer are encrypted by my own, super-secure, methods

and after every backup they are also in backup devices.
In addition, ofc, there are 50+ accounts, which are even less important, some web sites are maybe used only once, twice. They just "are". Maybe they would be appropriate accounts for those pw managers - but not those bank and other important accounts.
"Most humans will never" ... but they also belong to that category, where is made those warned clicks...
Good for you if you have 8 different passwords that you remember.
It doesn't change what I said. Some CSPRNG (crypto secure random generators) are perfectly secure and do better job with randomness than any human -- including you.
Everything you do online depends on CSPRNG already. For example, you have 8 passwords but when you go to 8 websites to use them, you see "https". " "https" would not be "safe' if CSPRNG wasn't working correctly -- as the key exchange mechanism for encryption relies on CSPRNG.
every time you use wifi, and everything you do online that is intended to secure.
What you said was still a bad advice. Most people should use password managers as they will be safer overall.
