I doubt this statement. I mean, obviously, dice, slot, and any other pure luck based games are easier than sports betting, because you don't need to think deeply or analyze something to be able to minimize your chances of losing. Unlike sports betting, you will need to analyze the odds, watch games to understand how the game works, be updated with the news around the league to better understand why the bookies came up with a specific odds, and a lot more things that you need to learn and analyze before placing your bets. Well, it could be easy if you just place your bets in any team and any odds and any type of betting, mindlessly. That for sure is gonna cost you money.
I think the easiest was coming from his own contest. For instance, if not now that gambling platforms are trying to make players to play casino games, we don't have much casinos games here especially the physical ones, we are not conversant with them and the alternative is sports bets and that's what many people play here and if you watch matches, you can make predictions easily even from the leagues you don't frequently watch bit casino games might probably need experience before one can win.
Sport betting also don't need much of your presence, once you are done making your picks, you can go ahead and stake whatever you can afford to lose on it and you are good to go, you can go and do your job, work and anything that will require your presence but that's different from casino games, if you are not there you can't win because you need to play.
