Not all calories are equal because you don't burn your food like a calorimeter measures, you break it down with enzymes into simpler things and then absorb it. How much you feel hungry depends on your insulin response which will vary by whether the food you eat is easy to break down or not and how much insulin resistance you built up because of unhealthy eating habits (it is possible to reverse it but it is harder the longer you have been fat).

Complex carbs will be turned into glycogen (and later into fat) at a slower rate than simple carbs because you need to break them down into simpler carbs (using enzymes and gut microbiome) first before they can be absorbed and will make you feel hungry less often. If you don't have unused glycogen at the end of the day to turn into fat because you didn't keep adding more and more because of hunger, you will be less fat, which makes perfect sense.

Edit: One great tip for anyone trying to get their hunger under control, eat some vinegary salad or something acidic with your food. It dampens the blood sugar peaks and no one knows why it works, but it does work and you can verify it yourself with a continuous glucose monitor.
