You aren't wrong in a technical sense, but this is far too reductionist. The type of calories and the way you consume them can't change the thermodynamics, but they can and do change your hunger, satiation and other bodily sensations that feed back into the thermodynamics by affecting your calories in and calories out. The simplest example is not needing a mid-morning snack because your choice of calories led to you being satiated for longer.
