This is subjective, but I would consider exceptions (in the Oracle sense) to be a subset of errors.
Errors would include these Oracle exceptions (no_data_found, a constraint violation, etc.) as well as business rule errors (trying to assign a student to two simultaneous classes, trying to delete a posted invoice, etc.).
The handling for each of these is dependent on the requirements and the context. You may return a soft message back to the app, a fatal error, or suppress the error entirely - it just depends.
