Well weight loss just comes down to energy balance. If you maintain a calorie deficit with diet alone you won't need to exercise to lose weight. If you are not in a deficit through diet then exercise will burn calories to put you in a deficit which will cause you to lose weight. So I do agree diet is more important. But the benefit of exercising to lose weight is that you can eat a lot more than you otherwise could if you didn't exercise which leads to better results in my experience.
"A lot" being one soda, or one slice of pizza. Even so they've found very active societies don't burn more than a sedentary American on average. It's theorized the reason is because your body compensates for exercise by lowering basal metabolism in the long term. Basal metabolism us 70% of your energy expenditure anyway so it takes a smaller drop to compensate than you would expect.
