You are too worried about getting addicted, it takes a lot of time before you get into that deep. But if you are that worried, it will only stress you out and it's best not to try further. It defeats the purpose of gambling as entertainment.
Most beginners I think first try that dice game and roulette and after a few days of losing, I'm sure they are also trying out strategies to win as what others are doing.
In gambling i don't play what i don't understand like dice and the rest i always go with football that i know very well very easy for me to predict, maybe one of this days I might try something new.
