Can you make a living off of games?

Is it realistic to expect a sustainable livelihood solely from playing video games? Do professional gamers actually earn enough income to support themselves and potentially their families? Are there specific skills or qualifications required to become a successful gamer, and how does one go about pursuing this unconventional career path? Additionally, are there alternative ways to monetize gaming hobbies or talents, or is it predominantly limited to competitive play and streaming? I'm curious to understand the feasibility and potential earning potential of making a living through gaming.
