Different types of calories are metabolized differently. Sugar intake impacts your blood sugar, given enough time can cause insulin resistance, which is the fast track to obesity. Limiting the proportion of your sugar and carb intake absolutely has an effect on your health, even with calories being equal.

There's really no such thing as different types of calories. A calorie is a unit of energy. 4.2 kjoules. Specifically, the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. That never changes.
You can get calories from different things, like carbs, proteins, fat, etc. And each of those have different levels of Calories per gram, and the body uses each differently.
But there aren't different types of calories. The "Calories in, Calories out" is a really simplified expression that is far from accurate because of how the body gets Calories from different things. But it's not an unreasonable guide to follow if your diet is balanced. If you want real accuracy and understanding you'd have to look well beyond simple Calorie in, Calorie out. But it's still a decent starting point to keep a rough idea of your intake.
