It depends on your requirements. I recommend you to write some basic console applications instead of game before you understand what is programming.

This is a great topic, there is no way to tell you all the concepts in such place. You'd better learn c# program$$anonymous$$g at least two months.

checkout c# Topics, your own classes are to define your custom game world, Unity scripting api just provides common functionalities among game program$$anonymous$$g like rendering models, camera view and math etc.

Unity API classes are intended for most of the rendering/ physics, transformation of game objects. Depending on each game or any Unity 3D app, you'll have to design your custom classes or object models.

Unity provides with all important needs to make any kind of game.

Each game will have it's own behavior which means the game objects will have their own behaviors, which you'll have to code using Unity APIs.

it is the developer's job to design or utilize the engine features as he/she wishes. In all scenarios, there definitely exists a case where you have to write custom code for your game logic. Examples include, camera behavior, custom collision detection for updating scores etc.

As a developer you'll have to create your own custom behaviors and reuse them if needed in any game.
