I think this is true. I think it's because we intuitively understand "being good at something" to be relative to "the people who are the absolute best at it," not on the total set of people who do it. I disagree when the post claims that "advice works". If someone gives you good advice and you manage to take it, you're still missing something. You're mising the intuition that led them to be able to give you that advice, which is the really valuable thing. This is why self-help is so worthless, even if it's good advice.
