For the US, no you are not "totally wrong". The majority of 11kW EV charge ports will have been installed by an electrician and also inspected by the local govt. electrical inspector because the vast majority of people simply do not try do to this work themselves.
However, in many locations in the US, homeowners are allowed to do their own electrical installs, provided they pull a permit and have the required inspection performed. Those should also meet code, as otherwise the inspector should have failed the install.
Which only leaves those who will do the install without pulling a permit and having an inspection. What percentage of the total those would be I do not know, but given that few do their own electrical work anyway, it is probably a very small percentage of the total. And a sub-set of those would do the install properly to code anyway, even without the permit and inspection.
