You clearly have very little to no practical training experience, and if that's you're "source" of information, then it makes sense.
Got me stopping mid-meal to post in response to your unlearned ass.

People who have been lifting for years and years need hours in the gym to make any gains. The longer you lift, the less your muscles respond to training. That’s why a beginner can gain 20lbs of muscle in a year but it’s impossible for someone who’s been training 10+ years to gain that much muscle mass naturally in the same timeframe.
Negged for posting misinformation. The bold you posted is actually false.
Mechanisms and Mediators of the Skeletal Muscle Repeated... : Exercise and Sport Sciences Reviews
Muscles become better at adapting to the stress of workout stimulus, not worse; the muscles aren't responding less, the requirements to damage them have increased because the muscles are more resilient. The CNS also makes adaptations over time, that's why a conditioned lifter that's the same height/weight as a noob will still lift more (well that, and having better technique).
An advanced trainee would almost certainly require more volume and higher weights to achieve the same stimulus, which could increase the number of sets they may do, but nowhere it is a given that the trainee must be in the gym for hours to make any gains.
You also neglected to mention that the person who has been lifting for 10+ years should be much closer (or even at) there natural genetic muscular limit than the newb who just started training, and that's primarily the reason they couldn't put on 20lbs of muscle in a year: it isn't physiologically possible to gain appreciable amounts of muscle after a certain point.

This ain't the lifting hill you wanna die on little dude.
