A calorie is a unit of measurement. In terms of how much energy you are consuming, which is what matters for weight gain, there is literally no difference between one calorie and another.
“Empty calories” does have a meaning and it’s that something is ‘just’ calories with no additional nutrients. Not eating any nutrients will make you sick, but not obese.
That’s not totally true. Nutrients can be more or less bioavailable depending on how they come. This includes calories. It’s a good rule of thumb to assume all calories are the same, but it’s not exactly accurate
