If there's any takeaway from this beyond not raping kids or molesting strangers, it's that being "pro gamer," like "streamer" or "Youtuber," is a hobby, not a career choice. The only exceptions are the best of the best, or rather the luckiest of the luckiest, and even they are in the single digits and had enough money to burn if they failed otherwise. Look at Nairo, the Smash player who was cancelled, and how he doesn't have any advertisable job skills or education as far as anyone is aware. Now he can't do anything beyond menial labor and entry-level work, assuming he fails trying to restart his streaming career.
Your ability to push buttons good at a video game will degrade over time and, even with sponsors, you won't make enough money to have a sizeable safety net for the future. You can have it as a hobby, you can call it your "lifestyle," but for your own sake, don't bet your life on it.
