I'd disagree here in that there are a small percentage of people doing anything that are incompetent. But not being proficient does not make one incompetent. Perhaps a bit more granularity would help.

incompetent < mediocre < average < good < proficient < expert

Most people, in any field of endeavor are average. That is the meaning of the word.

See above.

The incompetent DBA is not doing backups or not verifying that their backups can be used to restore and recover. The mediocre DBA is writing shell scripts to do backup and tested it once. The average DBA is using RMAN but doesn't really know the tool except to repeat, day after day, what they did the day before. The proficient DBA, like Sybrand for example, has knowledge of the underlying built-in packages and the tables storing metadata in the repository. The expert writes RMAN scripts, without the aide of websites or books, capable of making the tool sing and dance.
