The best thing to become a 'successful' gambler is to understand you will 100% lose everything if you let your feelings get the better of you.
learn to have self controll and know when to stop, dont rage bet into oblivion and set yourself a limit before each session.
Ultimately it is down to luck, learn how to manipulate that luck and learn when to not push it to far.
Even if you follow thos guidelines which are great to know for each gambler in the end this does not guarantee you will be a successful gambler.Gambling is based on luck and the house edge will stop anyone from being a successful gambler.There are only lucky gamblers and are the one who win big during their playing session.
Gamblers like you who strongly believe in the fallacy of gambling as a game of luck have been the ones enriching casino operators. I have been at a casino center where I saw gamblers furiously scribbling down the previous number on a strip of card and there are times gamblers frantically scour the casinos digital board to display the last digital numbers all in an attempt to get lucky lol its quiet humorous.
The house edge will not stop anyone from being successful unless those who are not strategic in playing, there is therefore nothing like lucky player but players that knows how to handle their games and as well stay on top of their game.
