I think between luck and experience 75:25 in giving victory. playing online or offline gambling the opponents we face, equaliy have experience, if against Bot, the developer surely make a Bot program that will not be easy to defeat by opponent. and match experience will not much affect for winning in every match.
so I think a luck is more needed than experience.
Playing against the bot will be a horrible thing we do cause it will never give us a chance to win, it is program already. We can see any chances of winning when we play offline or against another players.
If we want to be a successful gambler, then we need to focus on gambling and spending more time in casino in order to learn a lot. But if we think that it can be easily achieve or haven't that wide adoption in gambling environment, it probably making you sick and quit.
