This is true.
I agree with that most bodybuilders don't need cardio. But very few people lack the discipline necessary to "eat clean" long enough to cut fat and lose very little muscle.
Look around most gyms in america and you see mostly two types of people
1. the fat slob, farely musuclar guy benching an average amount of weight but at 35+ BF, no one cares. So he has convinved himself that the is power lifting. Doing mostly 1/4 reps
2. The normal looking guy that swears he is Ronnie Coleman's twin walking around with next to nothing on. Put a tshirt on him and couldn't
tell that he works out. Doing mostly 1/4 reps
3. Very seldom seen..that is the guy that has figured out a few things about him self and is making gains
