Perhaps, but it is that 20% of error messages that leave people believing that they are unable to handle the other 80%.
Part of the problem is how error messages are presented. A lot of software uses tools like modal dialog boxes to present everything from "a file with that name already exists" to "the file cannot be written". The former can easily be handled. The latter may involve a call to technical support (and part of the reason for that is the ambiguity of the error message).
