You will get better handling the card and having a good poker face but that won't guaranty a win, it's still a game of luck if you will learn a skill where you can read your opponent's mind, now that's the skill that will get you a lot of win in poker.
It will help you and improve you to become better for having a poker face though. Joking aside.
Improvements will be there and you know how to take care of yourself regardless of what cards is in your hands.
