Very much depends, not an absolutely true. Other commenter’s example is good: I can absolutely cook better steaks than all but one restaurant in a 30km radius. Pizza, sushi, most non-fish seafood? Not so.
But truly the biggest win here is that you can choose what ingredients you use, and that usually results in “better” food than the restaurant simply because it’s cooked and spiced perfectly the way you like it.
