These two sentences are not mutually exclusive.All this says is that it sold over 60% of its copies on pc in the first few weeks, beyond that you are making up your own story.
You claimed it would have still been very successful on PS5 without the PC sales.
We have data saying it wouldn’t even be a top 20 all time Sony game without the PC sales.
Beyond that, Top 20 "All time" grossing Sony game is amidst a lot of games. You claiming the game would be a flop if it didn't sell on PC is on the contrary the one with little to no evidence. That's just a loose assumption you made because you heard it was a hit on Steam. Everything we know publicly points to it being the opposite and that they were close to each other.
What you're implying is only true if you just exclude literally everything else pointing to the opposite.
