As long as you have at least average genetics (more or less) with grinding you can get to a top level For example, if you’re like 195 cm but dedicate every bit of your life to basketball you’ll probably be better than a 220 cm guy who rarely even shows up to practice. Obviously you won’t be shit tho if you’re like 170 In csgo anyone who grinds the game for over 8 hours a day and practices correctly can get to tier 2 (because tier 1 is more luck based) Genetics only start to kick in when being the absolute best player in anything. Most of the “best players” are a combination of hard work and talent, like s1mple for example. No matter how hard you grind running you might make it to the olympics but it’s very unlikely you’ll break Usain’s record.
