It's not quite that simple.
Chemical bonds require energy to break. Simple carbohydrates are MUCH easier to destroy than fats and proteins. Over-eating simple carbohydrates more readily creates a caloric surplus and ends up leading to the body storing excess calories as fat.
In the end you are correct, but maintaining a proper balance is the key to not having a surplus. Eating more lean protein and proper fats is more filling and therefore makes it easier to prevent over-eating.
