We would be so out of it to even call it a profession.
Like, we would have people whom would just wake up for the day, clean themselves up, get dressed and walk out the house and tell their spouse that, “I’m going out to work, playing poker for the day”? I sure don’t think so. It can’t be a profession, gambling. Except for the game offerers and bookies though.
And yet we do have people who are professional poker players and that's what they do for work. They can earn good money with their skills depending on the type of games and tournaments they participate in. Plus there are sponsorship deals which help them in times when they aren't earning much or when they lose. With the popularity of YouTube, I am sure it helps if you are a streamer and you post gambling content where it's allowed.
