In the end, it all comes back to you or what is meant is depending on how smart you are in managing money and controlling yourself, although many things can trigger various more aggressive actions outside of the influence of emotions but when you understand the impact of for example consuming alcoholic drinks then you should not consume it or at least only consume a little so that you don't get drunk and so that your decisions in every bet do not exceed your capabilities.
As for the alcohol drinks, I think it is still 50:50, back then when I still take a drink on casinos and with a lot of money to play, I will go YOLO on some games like slot machines and do max bet. There are games that due to the effect of alcohol, I won big like $5k-$10k in just one sitting. However, I wouldn't recommend it as we all know that it's just luck on my side perhaps and those drinks could really distort your decision making.
So just ignore those free drinks around, for sure you can buy it as well, but not in the casinos as the effect could really be that bad in the end and you will wake up in the morning really don't know what happened to you and how you lose the money that you have.
So yes, the result is still 50-50 because casino games depend on luck regardless of whether you play while consuming alcohol or not, but what I mean here is that the influence of alcohol can really encourage a gambler to make impulsive decisions without any consideration so that when it turns out that at that time luck does not come, it is clear that they will lose a large amount of money, and I think from some of your ideas in the last paragraph I can see that we are on the same page in responding to this.
It's never been that recommended that you are drunk when playing gambling yet most likely you will be impulsive when you do lose on which this might cause up on making deposits even more,and since you are in a state where everything is numb then you don't have the feeling on spending money but in tomorrow's where everything is normal then you will be having those realizations that you have done something stupid.
