Apparently sports betting involves so many tactics but the majority of it's game is based on luck...
No, sports betting is not the same as a casino, where in most cases your winnings will depend on luck. If you are well versed in the sport you are betting on, then your chances of winning will be significantly higher than if you were choosing a result at random.
You talked about the word "CHANCE". That "chance of winning" brought in the luck he's talking about. Although elements of luck may be low in sport betting when compare to other betting but it can't be fully erased. Have once mistakenly played "home or draw" instead of my prediction which was "home or away". This mistake made me won the ticket. Predictions is not /00% accurate, this made luck have it way into sport betting especially when playing an accumulated bet.
Not only in accumulated bet both in single bet, because there are some people who always base on a single bet and they will still end up experiencing lose. So whether accumulated bet or not so far as is gambling, of course luck always play it roll. even if you want to apply the whole gambling skill, You will definitely experience lose one day, so the fact remains that gambling is just a luck based.
