I would say it all depends on age, lifting experience, genetics, and any other factors that cause some to respond to certain things and some to others. Though it is a very good assumption that you have to lift heavy to get big. Nobody is going to have open pro bodybuilding shoulders doing light weights. It just won’t happen. It’s why people who do calisthenics only ever get so big. It’s not until weight is added that you actually start to grow.Yes, genetic differences in the acromium positioning and shape are a bitch.
I agree, you definitely can but there are more variables involved.
Saying a black and white statement like "doing lateral raises 4x a week will get you snapped up" is also grossely innacurate and nocebo-ing. That's my beef with @NLM36 , no matter how hard he's trying to twist my words.
