Earlier quoted context omitted.
A non-trivial amount of their ARR is still from Valve-made games. Counterstrike still nets a bit over 1b per year from just case unboxings, and Dota is in the hundreds of millions. I wouldn't call 8-10% a margin of error.
Those are maintenance + loot box on existing games. Sure, it still takes art and craft, but not the same kind of development work.
