Surely the correct strategy here is for the human players to collude to give as much money as possible to a single player and then split the money afterwords, no?

Also, the fact that they players can only gain money without losing anything likely changes their play somewhat. By default I'd assume (and have generally observed) that most players on a freeroll (or better than a freeroll really) tend to undervalue their position and gamble more than is usually wise.

I'd definitely be interested in seeing a "real" game where the humans are betting their own money.

The four humans were getting $120,000 between them. Their share of that was dependent on how much better they did than the other humans. That means there was no incentive to collude.

Top pro poker players understand the value of money. They weren't treating it as a freeroll and anyone that has seen the hand histories can confirm that.
