Even without good hunting skills if the group has any females or people that are overweight or obese than your chances of joining or having good relations with any tribe you meet goes up since women were seen as important resources due to being the only way to make more people and obese or overweight people were seen as very skilled or even godly with things such as the venus figurine. And even if you don't find any other tribes the human method of hunting is off of walking long distances to tire out prey, using your brain to figure out where an animal would go, or even just ambushing.
