It also decouples the code that uses the system from the details of the subsystems, making it easier to modify the system later.Also, what is important while learning design patterns is to be able to recognize which pattern fits your given problem and then using it appropriately. It is a very common thing to misuse a pattern or trying to fit it to some problem just because you know it.
Be aware of those pitfalls while learningusing design patterns.
