We lose only because we do not understand the randomness. Every bet gets good, bad, average, very good and worst times. Trying to win in every scenario makes mostly a loser. Those who do not want to understand all these, may take their bad luck or their entry or late exit at wrong moments as the reason.
It is fair to say, and makes sense too, that good luck and bad luck each have a probability of exactly 50%. At least for the game of roulette. There is no proof that one can be more than the other. In the long run of course. The problem is that even with good luck (hitting the target number), you still lose units. You only get paid for the winning number. The rest of the chips, on all other numbers, you lose. On the other hand the casino even with bad luck still gets paid. It pays out one number and WINS with all the other numbers. With many players at the table, it turns out that the amount of chips shoveled into the collection slot are usually more than the chips paid out for one winning number. Sometimes the payout is higher, but overall they collect more than they give away. The 2.7% or 5.26% HE is a very small guaranteed profit, compared to the huge quantities they shovel into their bank. Spin after spin after spin.
So if a player bets 10 units and wins, he doesn't win 36 units. He wins 25. If he bets 20 units he wins 15. If you do the math, the price you pay to win, is a lot more than the HE. Only by playing 1 number you deal with the HE alone. In all other cases there is price you pay in order to win. All it takes is some bad luck to come along to wipe out all the winnings and/or your bank roll.
LUCKILY, roulette is the type of game, where you don't have to participate in every spin. Theoretically, if you place a bet during your good luck period you win. And during your bad luck period you lose. Playing non-stop it will surely lead to loss. Not only due to the HE, but also due to the lost units, even under winning conditions, because since good/bad luck are at 50% odds, it's not hard to figure that. You lose some even when you win (good luck) and you lose it all when you lose (bad luck)
. The question is do we know when is the time for good luck and when is the time for bad luck? Advance knowledge of luck is impossible. But that doesn't mean that we can't create CONDITIONS to make this parameter known. What is known is the fact that good/bad luck is a self balancing process. In continuous play this balance results in a loss (for reasons mentioned above).
However, if we force BAD LUCK, but COST-FREE, in a series of continuous events, it's only logical that the as the series continues, GOOD LUCK will definitely prevail over bad luck, especially if we only target 1 event only, where the winnings are higher than the expenses
. Then we start the same process again.
For a smart member/player it's not that hard to figure out how to create COST-FREE BAD LUCK so that good luck will be guaranteed when we actually enter the betting.
