While 12 hands is a small sample size, it's still enough to be significant. Obviously, it's normal to be a couple of wins away from the expected number. But it is statistically significant when you only win 2 out of 12.

Suppose you were rolling a die repeatedly, and 10 times out of 12 you rolled either a 1 or a 2. It's pretty damn unusual, and it would make most people suspect it was rigged.
