In my early days at gambling, I knew nothing to the analysis of the game or what the odds meant and made my selectors based on multipliers and luck to see me through but guess what, you’re damned right it was a lose. In as much as you wish to have some luck at gambling, you’ve got to do so within reasonable markets. You play the game based on possibilities that are most likely rather than those that have a higher probability of not turning out as the result.
This is most peculiar to the bookies though but yeah, it’s how you end up not loosing every time.
You can start with no experience, get more experience with time, discover something like secret patterns and math behind games, odds and casino bankroll but gambling is what it is, gambling. This means it's risky and very unpredictable so that there is no chance for any gambling strategy from what you experienced and observed can work perfectly and guarantee win for your bets.
Be experienced is better than be inexperienced but this only can help you managing your capital better, reducing risk and somewhat increasing your win/lost rate but it will never guarantee win of your bets.
