Question about acting?

So here is my problem. I live in Croatia, in Europe. I want to become actor. My problem is, I want to act in films, series, and make it big some day. But in Croatia, there are not open casting calls, like in LA or NY, and there few acting academies, and if you want to get in, you must either be very lucky, or have a lot of money -.- and even there you cant become actor in , lets say America. Should I give up or what? I mean, I want to make my dream come true, but what are chances for me to get in America (I am not rich -.-") and become famous. In fact I dont even need to be famous, but I want to act in films and series, in LA. So what should I do. Btw. im 16 and I dont have any experience in acting.
