Not in all cases, it honestly depends what the intended goals are. Even if I eat good foods, if I eat too much (calorie wise) I will still gain weight. The quality of food will have benefits to overall health, but in terms of weight loss it is abuot caloric deficits + still getting recommended daily vitamin intakes
HOWEVER, you are right in some degree, if you eat junk, which naturally has more calories in it, it will be harder to create a deficit without starving yourself at some point. Say I eat a whopper and fries for lunch, which has an obscene amount of calories in it, let's say 1000, in order to create a deficit (let's say 2000 is maintenance) i'd have to eat less than 1000 calories the rest of the day in order to get even the slightest of gains. Most people will still eat two or three other FULL meals which would put them way over. SO eating junk is partly a cause but not for the reasons you stated. If I only ate one whopper every day I'd lose weight but I'd be unhealthy as fcuk. See what I'm saying?
From the OPs perspective he doesnt have any knowledge of nutrition so rather than focus on limiting himself to small portions of fries and pizza he should overeat broccoli spinach and other veggies that are not calorically dense while eating solid portions of fat and protein. I don't think it is even possible to overeat some shit like celery so if the op wants to munch all day he can do it that without effecting his weight loss goals.
You have never seen those reality shows about fat people losing like 150+ pounds in a matter of a couple of months? Their "genetics" looked far worse then yours. It's all about proper diet and dedication to an active lifestyle. You have the internet, there are a million of great advices on the web about nutrition and effective work-out routines.
It's about YOU being committed to changing your life; for some reason I don't think you have it in you just by the fact you're blaming your problem on your genetics.
