I don’t have this mentality, no. I can sort of understand why some people do though. All gambling is about luck though, sure you can go with favourites or whatever but if luck isn’t on your side you won’t win very often.
I feel that as beginners no one really is 100% confident that they will win and we all close our eyes and bet even if we bet on something that is likely to win anyway. Your mistake as a gambler would be thinking that you will win for sure. There really is no guarantee no matter what the bet is.
There’s nothing wrong with betting on a long shot though. It’s likely a lot more likely to win than a lottery ticket.
It is similar but if you want to test out your luck then why not?
