Unity comes with a 3rd person character package - just install it and drag the 3rd Person Controller prefab to the scene. The 3rd Person Controller is inside Standard Assets/Character Controllers - if you can’t find it in your Project view, install the package with menu Assets/Import Package/Character Controller.
