Common assumption. Fairly incorrect, though. The truth of the matter is that, speaking from experience, as long as you don't shoot yourself in the foot by trying to go super cheap while building your system, you're unlikely to need to upgrade anything for about five years, if not more, depending on the type of games you play.
On the other hand, if you do need to go cheap on/skip out on one component early on, with the intention to add it on later - you can typically do so with minimal fuss, and generally without the level of additional expense required by a Playstation 4 Pro, or XBOX Scorpio. That's what Wodahs was actually saying, though I'm guessing that you actually understood that.
As for console games just working... I dunno, it seems like any time I boot up any of my consoles to play a particular game (not terribly often, I admit), I need to wait through at least one system update, followed by at least one title update, whereas all of my PC games update themselves in the background, due to my PC being booted up already for non-gaming tasks.
Not to say that PC gaming is inherently better than console gaming, or saying that there's anything wrong with preferring console games over PC games, nor am I trying to be a jerk, but your joke was a bit lazy. Gotta aim higher than that.
