What about that phrase made you interpret it as "everyone"?
This makes it sound like your young and still had the metabolism of a teenager... Losing that is what makes most people gain weight. While some people can be overweight with it, it's still literally the easiest time in your life to lose weight.
It would have been much harder if you were fully grown.
From my own experience I'm approaching 40 and I can estimate my weight based off the calories I've consumed and how much I've worked out since the last time I weighed myself within a couple pounds. It's not exactly in line with any of those estimator apps but it is fairly consistent I assume this is because I have a slower metabolism. Pretty much everyone I know who struggles to lose weight makes terrible choices even when they're trying. You can account that to cravings or impulse control or whatever but everyone that stuck to an appropriate plan has succeeded. It's a matter of figuring out how your body works and sticking to a plan but it is not easy.
For you, yeah.
For most people even, sure.
But not everyone, there's an absolute shit ton of natural human variation on top of conditions/diseases that effect that.
Like, some people react to a normal diet by their body drastically cutting energy expenditure to try and maintain fat reserves.
Billions of years of evolution says carrying around as much fat as possible is the optimal choice, and different people have different traits to maintain those energy reserves which used to be the most important part of physical fitness.
Like, of any possible addiction, an addiction to a high calorie diet should make the most sense to people.
That's where the part about understanding how your body works comes into it. It's certainly harder for some people than others but your body cannot maintain fat without the building blocks to do so and you can restrict these between diet and exercise.
