If you look at the leaves of a tree, they are seemingly randomly arranged. We call it chaos. If you take 100 pennies and arrange them on a flat surface in rows and columns of 10 it's called order. We assign the label chaos to something that occurs naturally and has done so for billions of years. Wouldn't that occurrence be considered order if it had been there a long, long time and the human species and our perceptions are very new in comparison?
The positions and numbers of branches and leaves of trees and plants are governed by Fibonacci series: 1,1,2,3,5,8.13 . . . . , so there is order in their arrangement. Whether this pattern exists seems to have little or nothing to do with how used to it we are.
