The emotions may not even be the ones generated from the pressure of the game or gambling, but emotions from external factors like family, friends, environment, and economy.
These external factors can contribute to the emotions that one feels and influence their decision-making in gambling.
It is important to stay sharp so you can always know when your decision is getting emotionally influenced.
Indeed, it is quite difficult. I find merit in your argument related to external factors influencing decision-making at casino tables. As a poker player, I have direct experience of what tilt actually is, and it is more dangerous when you channelize your emotional disturbance through gambling. It is a 3 Michelin star recipe for disaster

A weak untrained mind will always be weak in every field, making poor decisions in gambling is no different.
