I see no problem staying in the midst of other gamblers to gamble. You know why? because most of them are gambling responsibly. If you are in the midst of people who knows the rules in gambling and abide to it, you will easily be influenced positively. We ought to know the type of gamblers they are before agreeing to sit next to them. Yeah you might even get lucky to win, especially when you guys share ideas, check flaws and try to collect them. You may never know a new things awaits you until you find out.
I think associating with people who are good at gambling is a good thing, not only you can acquire and know their ways on how to win on gambling, this people are committed to win and not just, want to have fun, but if you are alone, there are things you need to learn first without any help and on the process resulting to a loss, but if you are always aware and is keen to details that is an advantage, but i would prefer having other people around but, still you have to decided on your own of course they are just their as guide, so that there is no blaming.
If possible, I'd also like to have friends who are good at gambling or who know how to win, because that would certainly be very profitable. But logically, I think it's quite impossible to find such friends, or even none at all. I mean, I don't believe there are gamblers who know how to win, because if there were, many casinos would go bankrupt.
What is possible is having gambling friends to share experiences that lead to larger losses, such as from aggressive actions that should be avoided, and learning from each other's mistakes to avoid unwanted things.
In gambling, the most sensible thing is to learn everything to minimize risk, not to chase wins.
