Well I think it's a sign that you need to be careful with your gambling activity because it may continue and might ruined your life when you become addicted. Probably you need to take a break for few weeks or months until you can manage your emotional first, if you have wife or parents in your house, don't deny their advice if they say your gambling activity are too far than it does.
It looks like the beginning of an addiction. It does not seem very serious at the moment and it seems that the OP has been gambling for some time now, responsibly, but it is the first time that something similar has happened to him.
The good thing is that you can get out of anything:
I am a compulsive gambler.
I did two intentional drug overdoses trying to kill myself.
I also suffered with acute psychosis along with ptsd for 10 years. I had a bad life style age 15-28
But I quit gambling.
stopped using drugs
met a girl married her in 1986.
still with her now in 2022.
So if my life is like a vinyl record after some shitty songs the rest are much better.
So you can help yourself. And make some good music 🎼
