Can I make varsity softball if I am a beginner but I work my butt off?

I would practice about 4 hours every day june and July. I just have a craze of Playing softball. I am going to be a junior next year and I am only gonna play sports for a year so I want that year to be in varsity and be lettered. Well I think my school team is really good and they also have reached the states and all the schools they play against are awesome too. So do you guys think I can make varsity if I practice a lot and find some kind of training( which is probably gonna be a cheap one)? And is it easier then other sports like basketball, soccer, tennis, track and volleyball? Is it a easy sport to pick up?
