consoles are more popular than PC by quite a big margin.
How do you measure this? Steam alone has 130 to 150 million active users, more than Switch customers at a whole. And that does not even include some of the most popular PC games at all. I also expect PC user base to grow, it has more potential than consoles.
So yes, its a big deal for companies like Sony to open up this big to PC and to be that successful. They don't even need to sell a console to sell games. Off course consoles will remain popular and for good reason. But most popular games are mulitsystem games and not specific to consoles anyway. In my opinion it is remarkable how much Sony focuses on PC now. I hope they keep doing it; its only beneficial for the players, the publishers and for Sony.
