Part of the problem with these stats is that depending on the state of the game the person might not even be trying to pick it up. If you need 2 pins to win, get the 2 easy pins instead of trying to pick up the hard spare where you might miss. The other thing is that pros don't leave something like the greek church very often. It was left 785 times in 447k frames. The data on picking it up just isn't that significant. It also means it isn't going to get practiced nearly as much as something more common. Also, there are more right handed people than left, and it shows in the data. mirror image shots aren't "easier," they are just easier for a certain handed player. As most are right handed, the shots that are easier for them will show up as easier in the stats.
