Exercise burns calories, eventually inducing ketosis, which burns fat. I'm not sure what you're arguing. To burn fat, you either need to burn more calories, or reduce intake calories. The videos you linked are equally confusing. There is no "debate" over diet vs exercise. They're both metabolic characteristics that interact heavily. If you tell a doctor you want to lose weight without burning calories or restricting caloric intake, he's going to laugh you out of the office. Arithmetic doesn't work like that.
