This is the reality. Everyone couldn't be winners in gambling. Most of us have to lose so others would get their chance to win. Casinos can't sustain to provide winnings for all their players so we have no choice but just to rely on our luck. Things will only differ on how we deal with the risks of gambling by knowing when to stop especially if we're already losing too much.
It's pretty painful to stop when you know that you are losing too much so there's a tendency that a gambler will just continue but there are instances that they got lucky and win huge before their balance gets completely depleted. I experience this sometimes and it's much easier for me to quit when this happened.
