I don't think many people try to replace stress or depression with exercise. If we talk about entertainment, gambling for a large number of gamblers is entertainment, but since it is a high-risk entertainment it can significantly affect the emotional background, which in principle can contribute to the deterioration of the state. Therefore, I also do not recommend gambling in stressful situations. It can lead to serious mental health problems. Play gambling when you are doing well and be sure to limit yourself when the situation requires it and then you will not have problems.
