I do sometimes cause I play live games. I’d check the stats, tactics, tension, and risk management of the both team then predict the possible outcome.
If we play online, those statistics are available to the user, if I'm not mistaken, so it's easy to track everything.
However, for those of us who play in land base casinos, I doubt that we will do it specially if we are just having some fun around. And I'm not seeing any positive for the gambling getting on how much they bet or how much they win or lose already.
Worst thing is that it will make them more anxious in my opinion specially if they see the spread of how much they've lost already. So personally, for me, I don't do it.
This is the reason why there are people get disappointed on the result shown especially if they see that they are losing to much than winning. They maybe quit for seeing that and curse those casino since they think that those casino is just scamming them. But if they are playing because they are interested on the entertainment factor it could bring then possibly even if they see on statistic that they are losing for sure these people will just ignore it and continue to gamble.
If gamblers can't afford to lose a lot then maybe they should try to make their losing streaks as a basis to quit since maybe realization will pop up in their mind that in gambling especially on a game of chance its hard for them and win some money so that times its better for them to decide if they want to continue or totally quit in this activities.
