I disagree.
The outcomes of individual occurrences within a sports contest are not random.
Fumbles and interceptions are a function of skill, not randomness.
The non-random qualities of the participants...skill, strategy and choices inherent in the game...determines the outcome.
That is why the exact score is not known before the game starts.
Players cannot impose their will upon cards, wheels and reels.
The outcomes of random casino events are mathematically convergent, so those games are solvable.
