Casino is way more risky for sure. In casino it's all about luck and sometimes RNG, while in sport bets you can predict better who might win now, because you can find statistics about team and players in that team, while best statistic you can find in casino is "lucky" numbers list, which is not helping you at all. Basketball game with 95% chance to win will probably win, while in casino you can't be 100% if you will win
you can bet 95% odds in casino as well. just bet everything on a roulette wheel except 1 or 2 numbers.
But chances that it will roll on that 1 number that you don't bet on is much higher than team that have 95% chance to win. Teams like this are usually stronger, faster and plays better than enemy team, and they will almost always win, while when you bet on roulette, ball have same chance to stop on each number so it makes gambling like this much riskier
i personally never like to place a bet on low odds like that , really not worth and feel so hurt when you have to face the fact that you lost it. always better to place bet on a 50/50 chance so the gambling thrill feel like so real , that is what i always do .
so far it is not make me get addicted so fast, at least did not lost too much no matter it was sportsbetting or casino betting.
