Player 222 is going to die if the writers know what they're doing.
The whole theme of the show is how capitalism is merciless to everyone, no matter your race, gender, circumstances, etc. Gi-Hun is shown to have won because he was lucky. I don't think Gi-Hun will win again, but I dont think it'll be 222 who does.
Gi-Hun could become the front man if he lives, but I don't see him winning. The show needs to avoid cliches, meaning the son needs to die before the mother, and 333 needs a brutal death.
