Without any doubt the riskier are casino bets, as this is pure luck, while sport bets rely on some external factor.
I agree. Gambling is basically a luck game, where we rely heavily on luck to win. But when comparing between casino and spor bet, I agree with you, casino is purely dependent on luck, while sport betting has other factors besides luck that can help us win.
There is no difference if you keep talking about luck, because whatever analysis and strategy you use in sports betting, all the calculated points are those of others, so you just rely on luck. Depending on who we prefer to master which skills, on this side I prefer something that is as straightforward as the casino offer, would be more risky for me if involved in sports betting that has a long time analysis.
