Chris Moneymaker got some damn good hands. Its part of the game. Its why this feat is unremarkable and why poker is a crap game for AI. The outcomes are very loose, especially when the reason these guys are pros is partially because of their ability to read.
You are taking away a tool that made their proker players great and then expect them to be a metric to test the AI. A better test would be to have pro players play a set of 1, 2, 4, 7 basic rule bots and the AI does the same. Then you compare differences in play. With enough data points you can compare situations that are similar but the AI did better or worse. This is a fair comparison of skill.
Also if there are professional players at a multiplayer game the AI is getting help from other players. Just like Civ V I get help from the AI attacking itself. Im sure this AI got help from the players attacking eachother (especially if they were doing so and making the pot bigger for the AI to grab up, think of a player reraising another player after the bot does a check all in).
