Hi Frank! There are two sets of really important skills for anything creative: storytelling and technical knowledge. You can build your storytelling muscles by writing and storyboarding—those are free and only require paper and a pencil. Technical knowledge will come with practice, for that I'd recommend looking into Adobe Creative Suite. They have a discount for students where you can get access for $19.99/mo. Once you have that set up you can check out tutorials for After Effects or Premiere and start bringing your story boards to life.
Hope that helps :)
