Well, there are 17,022 player IDs in the Lahman database. If your 16,631 represents only non-pitchers that would leave only 391 pitchers in the history of MLB. Now these tables for batters and pitchers include anyone who has gotten a plate appearance or threw a pitch, so they don't discern whether they were considered a pitcher or a hitter. Still, your list would almost have to include pitchers, unless I'm running the query wrong or your source is more complete.
