It's not that "anybody can achieve anything", but that we can almost always get far better at almost anything if we put effort into it.
E.g. I do powerlifting to stay fit. I don't think I'll ever be a world class athlete, but through consistency through the last ten years, I'm lifting at an advanced level for my weight/age class on all my lifts.
Could everyone do that? Probably not. Thought most people can likely get to my level with enough effort.
More importantly, every untrained person can improve massively, because the average untrained person is so massively far from their potential.
I lift 10-15 times more today than I did when I started. Unless you've got severe health problems or disabilities, start at a very advanced age, or a very good starting point, most people will "easily" be able to increase their lifts by at least a factor of 5 in a few years with 30-40 minutes 2-3 times a week. In fact, most total beginners can double or even triple their working weight within a month or two.
The same applies for most mental disciplines as well: We may not all make it to expert level in every discipline, but we can almost always multiply our starting skill level enough times over with some effort that most people who have not put in any effort in the field will be impressed.
