Gambling is all about luck and sometimes skills matter too. It depends on what type of game someone is playing. What type of gambling are they doing? It could be Sportsbet. Betting on sports everyday isn't bad especially if you know which team is stronger. You have to be up to dated with the team news like which players is available, if any team missing their key players or not. These things affects on the game as well. Sportsbetting does not required a lot of time to place a bet. If you could place one or two bet a day which may take an hour to research about the team and place the bet.
Although some gambling games require certain skills, but it can't be separated from the luck factor as well. So, I assume every gambling game is about luck, we don't too confident with our skills to always win the gambling. Winning betting sports also needs luck, although we can do analysis for the matches but the result can be surprising. We can see that many matches have unpredictable results. The favorite teams or players don't always win the matches. So, if we are unlucky, we may experience this.
Anyway, it is true that joining sports betting won't spend a lot of time. But we need enough time to analyze the possibility for the matches. No one just places their bets without analysis. If it happens, the chance to win will be very small and we only rely on the luck.
