I am one of the top reviewers on all queues except Suggested Edits, I hardly ever see any. I am doing review queues every time I open a new browser tab (its my default new tab), yet I only have had 94 (At time of writing).
Is there something else limiting this, as people who have been doing review queues for about the same time have hundreds.
Or is it just plain luck?
Further in contrast, I get a lot of first posts, and an average amount of the other categories.
