Personal example: growing up I practiced the piano for about a decade, 30 minutes at a time, usually 4-ish days each week. I got more disciplined about it as I got older. After 10 years, I went from not being able to play at all to being able to play genuinely impressive stuff. I'm not especially talented, but the consistent application of 30 minutes at a time really did add up to something wonderful.
No survivorship bias needed here. Anyone with access to a keyboard or piano could have done the same thing. Yes, you would've needed to want to learn to play at least a little, and yes, you would've needed to practice at least a little intentionally, but given those things, just showing up consistently over a long period of time can do wonders.
