The principle of what you're stating is true, it could be correlational.
But there's an enormous volume of evidence that exercise, especially intense exercise, is better for health than any other intervention, including more sleep, quality of diet, pills+supplements (except those that treat an active illness/disease of course).
There's even compelling data showing that moderate drinkers who exercise live longer than non-drinkers who don't exercise. Even given that Alcohol is a powerful carcinogen.
The only thing proven more effective than exercise is weight loss really, if starting from high bodyfat levels.
(Anything above ~15% bodyfat in men seems to have negative implications for lifespan, and ~30% for women)
