A small team of human plus a huge datacenter trained on stolen resources. It’s like someone claiming they can assemble a car solo but didn’t disclose they also use multiple giant machine and a factory to do it. The factory is impressive, but the person doing it is insignificant, because that factory isn’t build by the one person, the car too.

So the game M$ made should mostly attribute to AI, the dev is insignificant. It’s not Halo Studio, it’s Copilot Studio that would be making your next Halo.
