Rick laughs at anyone who spends money at the slot machines, because it’s a purely aleatory game that has no intellectual component whatsoever.

Gambling is aleatory in nature because a payout occurs based on an event outside of one's control.

We insisted that the coin toss be completed five times in a row by five different people, ensuring that the results were completely aleatory and unpredictable.

Although the throw of a die is supposed to be entirely aleatory, Gregg seems to know how to spin sixes every time.

My opinion is that a truly aleatory situation is never possible, because everything is based on cause and effect which is anything but random.
