In some way, you're right, but I think there's more to it. Let's ignore for a moment whether it's true. I've seen it said in the sense that if you eat too many "good" calories (from salads or other healthy foods) and spend the same, you'll get just as fat as from bad calories. So the money analogy in a way works - if you get $100 cash, you'll be just as rich/poor as if you get them via a bank transfer. All of that glosses over a million details, like how full you'll be feeling after 1000 cal from salad vs 1000 cal from Coke, but that's a whole another can of worms.
