In my opinion, it is clear that experience in gambling will only be useful to minimize defeat...
It is clear that gambling has a higher concentration of luck ingredients than it has for expertise, skills, technicality or experience. However, your experience doesn't account for nothing entirely if luck doesn't play out to your advantage. You can use your experience to know how to avoid games that will most definitely not be profitable to you and that alone can be said to be success in gambling.
The more effort we put into gambling, the faster we could be making nice profite. Gambling is adding more flavours every day with new games and new patterns of betting. Once we know what we are looking for and how to go about it, our curiosity is solved partially and it is now left for us to go into it fully. Luck is a game changer for people that knows how to attract luck for themselves.
We don't need to merit it, all we need to do is to work on ourselves and recreate a better target for ourselves.
