That's ignoring the trees for the forest and saying that forest growth and death patterns are entirely inexplicable because the system is too complex.
Psychologists use statistical models because we lack the full understanding of the brain, but that doesn't mean that behavior can't be predicted if we did have a full understanding.
Saying that the rock rolling down the hill has a distribution pattern completely ignores complexity. Did it have the same exact starting point each time? How strong was the wind blowing and in which direction? Did a pebble move out of the rocks path from the last run?
If all conditions of the rock rolling down the hill are exactly the same that means that the rock will take the same path each time. Differences create that statistical distribution.
