On its own, at best it's a solid mindset to have. There's defo been times where I've been stuck because I simply was playing badly. I knew what I needed to do, I just wasn't doing it. At worst, it's vague and dismissive and therefore very unhelpful.
As a summary of advice given, it's far more helpful. Sometimes when you're stuck in a game, it's because you're doing something wrong. Those people need specific advice like "Go level up a bit more", "Do this to avoid that attack" or "Complete this quest to nerf the boss". Other times though, some people really do just need to do what they already know better. It really is just a skill issue and the only useful advice is for them to git gud. For example, there's a lot of tricks to help with Malenia in Elden Ring, but you still need a certain amount of skill even with all of those.
Not gonna pretend it's not a useless meme the majority of the time though.
