Mastering a skill doesn't imply being in the top 10 or even 100. It simply means acquiring expertise to a point of diminishing returns and being recognized by your peers as very skilled. It's perfectly possible to become really good at chess and at the violin after a lot of practice. Good enough to impress a beginner. Learning a second programming language isn't really learning a new skill, it's maybe more like learning a new genre of music if you already play the violin well, or learning how to play speed chess once you're already a master.
