Dude, you need to work on your grammar. This post is illegible.
Anyway, the only way to get better is to practice. Those guys got to be professional players at the game by playing all the time, 10+ hours per day. In fact, the fact that they had to switch from Dota to Dota 2 was almost a disadvantage, having to relearn some things. If you practice all of the time, you will certainly become a better player. There's no reason you can't be as good as them since you never played Dota 1.
