Djokovic is describing neuroscience, not parenting philosophy.
The prefrontal cortex doesn’t finish maturing until age 25. This is the area responsible for judgment, impulse control, and planning.  Between the ages of 10 and 25, the brain undergoes changes that have important implications for behavior. 
Here’s the problem: dopamine levels in the limbic system increase during adolescence, making teens more emotional and more responsive to rewards.  The reward circuitry is running hot while the brakes are still being installed.
Laurence Steinberg, one of the world’s leading adolescent development researchers, likens this to engaging a powerful engine before the braking system is in place. 
Now add a phone. Infinite scroll. Push notifications. Variable reward schedules engineered by thousands of product managers optimizing for engagement. You’re flooding a system that’s already hypersensitive to dopamine with the most potent non-pharmacological reward delivery mechanism ever invented.
As prefrontal dopamine fibres continue to increase in density during adolescence, they may be particularly vulnerable to external influences, both positive and negative. 
The delayed dopamine connectivity in the prefrontal cortex during adolescence may underlie the heightened risk to develop mental disorders.

The “everyone else has one” argument his kids make proves his point. The social conformity pressure is a feature of the developing adolescent brain, not a reason to give in.
Djokovic has trained his entire life to resist immediate gratification for long-term performance. He’s applying the same model to his kids’ brain development. Let the hardware mature before installing software designed to exploit its vulnerabilities.
