Yes, Kubrick only directed 13 movies in his life and 12 of them made it on the top 5000 list.

Well, he made only 11 real movies (Killer's Kiss doesn't count IMO), and all of them are listed. So, I think the parent was implying that he's probably the only director with 100% "hit ratio".

These include some (in Frank Welker's case quite a few) TV shows, but even filtering for film all of them have more than Hitchcock.
