I think that's more because you are familiar with the original ordered state of the racked balls. If you take out energy lost to friction and heat and allow infinite time, after breaking the balls would bounce around ricocheting ad infinitum, eventually forming the racked state momentarily before continuing into chaos. Just like the monkeys on typewriters, and more frequently broken clocks.
By chance yes. But the frequency of events of order to disorder is less than order to disorder, because ultimately, the universe tends towards entropy.
