Chance refers to activities in a three-dimensional universe, that are beyond our realm of our present ability to predict, and chaos refers to activities that are so intricate they are beyond our present abilities to measure as they occur.
God IS capable of setting in motion a series of seemingly "random, chaotic", interlinked events, throughout millions of years, that eventually yield exactly the position where we all are now.
Because man reaches his limits well before his being able to understand or even participate, he regards these activities with contempt and gives them derogatory labels. But these still are God's rules at work, every minute step of the way.
You could say that, even if your parents happened to meet entirely by "chance", your own existence was actually planned in detail from the first moment of time.
