Albert Pujols 2,000 RBI. In how many At Bats?

Albert Pujols hit his 639th career Home Run May 9, 2019 to reach 2,000 Runs Batted In (RBI). How many At Bats (AB) did it take Pujols to reach 2,000 RBI, especially relative to others with at least 1,800 RBI?

Lou Gehrig had the fewest AB among players with at least 1,900 RBI.

Ted Williams had the fewest AB among players with at least 1,800 RBI.

So what good does it do to consider AB? It's a lot better than staring at the total with no context. Here are batters with at least 1,800 RBI sorted ascending by AB/RBI.
