I’m definitely a lone bettor. I do it to have fun. I think of it as entertainment and nothing more. When I watch sporting events it just feels like you’re on the team in a strange way when you’ve got skin in the game. Gives you a reason to celebrate as well. Who doesn’t like ordering a round for the bar after a big win knowing it’s paid for by the team. 
I am also a lone bettor myself. I prefer to bet on my own terms. Not a competitive one when it comes to betting. I only disturb myself on this simple pleasures of life.
Also, being a lone bettor, I don't have to worry about my bets or the amount of bets in place, that may somehow other people are looking at.We are the type of person who trust ourselves in gambling, we learn our owned way and if we improve and we become consistent, we can only keep it ourselves and enjoy winning in gambling. No pressure also as there's no people that will judge us but ourselves.
