Consider throwing 20 dice. It is certainly a random process. And we know the odds for throwing 20 sixes is about one to 30 000 trillion, so you'd have to keep throwing dice for about as long as the Earth has existed to get that result.
But if you start throwing the dice and you keep all the sixes you get along the way, Yahtzee-style, we expect you'll have 20 sixes in about 25-30 throws.
In the latter case, external selection has turned an incredibly implausible result into a certainty.
