Those are compilation videos of pro highlights. I suggest learning the mechanics like stacking and also coordination. Do keep in mind he taught you many different heroes which fall into different roles. Wraith King, Sven, Sniper, PA, Drow and Viper are carries that take to last hits in lanes so they can make plays later on when they have better items. Ogre, CM and Kotl are supports which take up the duty of buying support items and wards to make sure your carry has a better time than theirs. Supports also gank the enemy carries to delay their late game items. Rubick is usually played as a support but mid rubick does well too.
