Thats exactly it. I think it was Phil Spencer who said he'd want Microsoft to buy Valve if the chance came up. In the same sentence he said he would buy Nintendo, too. In the same way a Gen Z'er might say "I'd like to buy a house someday."
I still don't know it. I don't have a huge amount of confidence in "a prominent figure in the Counter-Strike community" as a source for Valve's internal finances.
