How do tennis tournaments work, and what is the process for players to compete in them?

Tennis tournaments are organized competitions where players compete against each other to win matches and advance through rounds. Players must register for the tournament and meet certain eligibility requirements, such as ranking or age restrictions. The tournament is typically structured as a single-elimination or round-robin format, with winners advancing to the next round until a champion is crowned. Players earn points and prize money based on their performance in the tournament.
