A lot of people are involved in developing a game: artists, game designers, programmers, testers, marketers, etc. A good first step is to figure out what you'd like your first role to be. Once you figure that out, a good second step is to attend college if you can. If you're looking to become an engineer, a degree in computer science or mathematics can be valuable. If you're looking to become an artist, an art degree can help get you in the door. If you can't attend college, consider joining a smaller gaming company in an entry-level non-technical role (like QA or customer support) from which you can gain skills and grow your career. It's definitely possible to laterally transfer from customer support and QA to product management in a smaller company.
I worked as a software engineer in the gaming industry for about 4 years. A word of warning: the gaming industry can be rough. There can be a constant sprint to meet deadlines . Wages can be lower due to a large supply of willing employees. Job security can evaporate as soon as a game ships or is cancelled. However, it also can be fun and exciting.
