Blake Sloan gave a kind and honest answer. The entertainment industry involves a lot of hard work, most of it is not glamorous. If show business is your dream, as it was my dream, get a good education, work hard, and be prepared for a difficult but rewarding life.
You're too young to apply, but you can still browse job listings for Walt Disney Studios. Here's a link: https://jobs.disneycareers.com/ The jobs that require degrees usually say so under "requirements". Some people know their calling from an early age. You may be such a person. But if you're not, make sure you've found something you love to do -- the job you're happiest doing is probably the one people will hire you to do. Your choice of school will depend on the sort of work you want to pursue. Today, an applicant with a science and technology education may have more options than one who studied art or writing. But, well, that comes back to the problem of discovering what you like to do. Try a bunch of different things.
Jolly holiday. Time.
