There's zero scientific proof to back your claim. There's no "stamina gene", it's not in our bodies. It's about what we do with our bodies, how we do it and what we put in our bodies.
Even when training with each other you will never find two people who train exactly the same with exactly the same mindset and intensity for the exact same period of time, eat exactly the same amount of the same food and breathe the same air in the same room.
Those variables are what the marginal differences between worlds class athletes come down to, not genetics.
