Players use different strategy to win and earn money from gambling.
If you are players that want to only enjoy playing well that's good for you ,but it will hard for you to win since you are not using any strategy like pros do.
Players multiply bet every time they lost that's why many of them win back the lost they get in just one roll or one game. But it's risky because you may lost higher if you do not win in that bet.
Strategies for winning do not exist in all games. For example, I have not yet heard of any winning strategy for playing dice or slots.
Many people make preferences based on their experience. If I have had the most luck playing dice and won there much more often than in slots, then I will choose the dice to play in the future. If someone on the contrary has won more often in slots, they will give preference to them in their choice.
I also play dice because it is much more fun and there are a lot of people to play with. However, there are people who do not like the presence of a large number of people so they prefer to play slots.
