Do you think I could turn pro in baseball?

I have asked this already a few days ago and I just want to have more answers. I am 13 now and I have been interested for a few months for turning pro now and I have always loved the game. I really want to become pro now and I want to know of what it takes. What drills and workouts to do for 13. I am hitting around 220 and tops 250. I play left field and I have a good arm, average speed and an okay glove. I can hit for contact and not as much for power. My fence only goes up 4-5 feet in my backyard and it's about 90 feet long. It also has a parking lot at the back which is fairly big. I don't live in a very big place only about 600-700 square feet. What are some good stuff to do inside and out? Also, I haven't gotten to little league yet and another question is do you have to play serious ball to get onto a high school team? How should I train in the winter? What do you people suggest to practice for MLB? Last and certainly not least, can I have the desperation and the talent to do it?
