De dicto and de re: narrow or wide?

Question

I think I understand the different interpretations of de dicto and de re, but this doesn't make sense:

de dicto is the narrow interpretation
de re is the wide interpretation

Isn't the following right?

John thinks the manager of Hudson Bank is rich.
de dicto: John thinks anyone who manages a bank would be rich.
de re: John saw the manager of Hudson Bank driving a BMW, so he thinks he must be rich.

To me, the de dicto reading was wide- he thinks any bank manager in general is rich; while the de re reading seems narrow- he thinks one particular person (identified as the manager of Hudson Bank) is rich.

Thank you! If you were able to answer my question, I'd appreciate it if you'd look at the other questions I'm asking today!
