It’s same with investing or trading when it comes to confidence with gambling. He is describing sports betting not a luck based games which means his confidence has basis depending on the match he is betting.
in that case i guess it is similar but i still think that sports betting might be a little riskier than investments or trading or any business really because in bets usually your money is locked in and you are not offered an option to take it back unlike with investing where you can take your money out whenever you seem fit
I do it as a gambler too. I place low amount of bet if I think I just want to try my luck on risky bet since I don’t have much confidence that it will win while I put high amount on matches that has high potential of winning based on my analysis.
if it is in sports bet anyway yeah it can be done since you will be using many data to come up with the analysis anyway
