Correct, Casino has a continuous profit through the house edge of the game. They deduct specific percentage on every bet win or lose. Simply, they profit more when your bet lose and they have less lose when your bet won. In the long run, Casino will always win no matter what happened because the odds will always in favor with them.
There is a saying. House always wins! If you are an old gambler, you may know about this. New Gamblers may get surprised about seeing this and may say, well, I am still in profit. I would say, Go on, buddy. We will meet again in the future.
Yeah, Most of the old gambler on play games like Blackjack and Poker to have a better chance of winning with playing the basic strategy. Some still playing slots but they are just doing it to hunt high multiplier using fixed bankroll unlike newbie that will chase jackpot without considering the total expenses of the bankroll. I’m not a regular player of slot games but playing it longer will make user just loss since it house 5% average house edge which is very high for a game that being played for long game session.
Beginners always counting just their current profit and forget what’s the real deal of gambling in long run. In result, they are always the users here that blaming or creating scam accusation against casino in retaliation with their losses.
