It is Schrodinger's Bob - Both technically literate enough to know how to do that, while also not being technically literate enough to spot the phish or determine why autofill isn't working/the password manager isn't matching.
This is where Passkeys shine, in an edge-case user that is neither of the two most common user types. Basically a unicorn situation.

you must not work in regular corporate environments. this happens all the time.
yes, they know how to hit the big "copy" button but don't know how to debug an extension.
take a year or two to work security (or general IT support) in a non-tech-company corporate environment, and get ready to have your socks blown off. people become exceptionally literate with things they interact with all day (excel is great example of this) yet have no idea that google.example.com isn't an official google website.
It's definitely not a unicorn situation.
Copy and paste is not a skill that requires much technical literacy. I've not seen a Password Manager that makes the copy button hidden or hard to find or need much technical skill to use.
Many "legitimate" websites, especially corporate "SSO", accidentally train users that autofill just doesn't work some of the time. Example Corporation's SSO configuration generally has users put their password into auth.example.com, except when the app in question is using some weird SAML flow and accidentally ends up at saml.example.com or auth.okta.com. An old legacy internal app still needs the password inputted in an HTML Basic Auth prompt due to a redirect through oldauth.example.com. The user learns to just copy and paste and have no idea why autofill works on some internal apps and not others because they have no idea what SAML is or why a legacy app is special/different from modern ones.
It happens on the public web, too, to a lesser extent. A website goes through a "rearranging deck chairs phase" and can't decide if id.example.com is cooler than auth.example.com or if they should just put login only on top level example.com and flip back and forth over a few weeks as different internal teams "win" or various A/B tests run.
