Gambling usually becomes dangerous when we exceed our limits, this is normal, as long as it is within control and limitations, it will not cause us any great harm. When control is lost, the harm will begin, and in the same way, when we start expecting something unrealistic from it, gambling is no longer entertainment, but it gradually becomes a cause of personal, family and financial loss. So the main thing is to be aware and be aware of the limits, here the bigger thing is self-control, not winning or losing, if you can't stop, the problems start.
Exactly, as long as you play the money you can afford to lose it doesn't become dangerous. The problem starts when you start gambling with the money you need to live. There begins the spiral of problems that takes you downwards, which takes you towards the abyss.
