Having many losses can leave people feeling discouraged; creating frustration and even disappointment
Over time, a losing streak can increase stress and self-doubt which can make gambling not fun any more.
Depression or frustration always increases when you are always playing for money. People who do this for fun or enjoyment never take this serious even in some cases, they left gambling for some time but joined again and had their best because they were well aware this was just for some time they could go ahead better in the future.
People who are involved in gambling for money and their own needs have enough frustration or depression with this to create serious trouble in their lives because losing money always increases their problems, and they feel frustrated that this is big trouble for them and their loved ones as well.
The question is, how many gamblers out there who gamble merely for entertainment? LOL
I will say that depression is normal when it comes to losing streak even if the amount can be considered as small amount only.
Those who claim themselves as gambling for entertainment, if they are willing to say honestly, I do believe they are also depressed (at least a little bit angry) when they are experiencing bad losing streak.
