Yeah, at the end of the day it's the odds (luck) that determine how often you're going to win.
Casino games are made so that you feel like you're winning even though in real money terms you're not. For example you see an amazing display, lights, shows, etc, but you just made a tiny amount of money. So you feel like you're doing way better than reality, and continue playing.
As long as you don't bet more than what you're comfortable paying, it should be fine, and seem almost like paid entertainment.
If you spend more than what you thought you were comfortable paying, then you will most probably end in ruin.
Some time ago I ran into this term LDW for the first time, loss disguised as a win.
Both the single-line slots (the traditional slots) and the more modern multi-line slots are programmed to give LDW “wins” in a specific payback percentage, but it is always less than 100% and certainly not above 100%, meaning that the house always wins. There are no “hot” slot machines, only “cold” ones.
From my experience, I can relate to this... When things go down they go down, there are wins here and there, but the balance is just getting lower. It's like that with all lucky-based games with any RTP & house edge. I have wins and losses on both, and I can't say that in "reality" RTP & house edge means a lot. But that's me and just my experience after millions of bets in all sorts of lucky-based games.
