Yes you have a good approach by only risking small amounts that you can afford to lose and I hope you can maintain that approach for a long time to come because after all that's the only thing that can keep us awake and away from any unfortunate eventualities like losing a large amount of money. And yes I like your thinking where you say that even though we are sure of our decision but it does not mean that we will win at the end of the session, and that is a good mindset and perspective on gambling where in addition to knowing that there is a chance of winning but we also realize that the risk of losing is something that can definitely happen at any time.
One of them is like the scenario that I have exemplified before when I saw the UCL competition in the semi-final match where initially Bayern Munich fans seemed very confident that victory was in their camp but in the end yes the last 3 minutes changed everything. So actually in gambling the various impacts of the worse possibilities depend on us in terms of managing our gambling activities, if for example from the start we understand that gambling is always about winning and losing then I think it is less likely for a gambler to eventually experience emotions and take various actions that endanger himself, everything comes back to the ability to accept facts at the end of the session, and that's why we are always advised to be responsible gamblers.
Risking small amounts to playing gambling will be better than use much money to avoids the big lose. That's already happens to many gamblers but they don't realizes that they must reduce their money that they used to playing gambling. We don't have to follows what they do because we must responsible with our money so we don't gets the same experienced as them. We can feels confident with our picks, but we must not feels too confident because we still don't knows what will happens in the end of the match. Even if we wins with our pick, we can't hopes that we can wins more in the next match because every match can't gives the same results.
The last minutes can changes drastically so we must be careful when placing the bet. We must realizes that our picks can lose anytime so we don't have to be seriously when placing the bet. If we can enjoy the match while we gambling, we will not thinks about our bet because our reason is not makes money but we wants to have fun by place a bet. We must prevents our emotion becomes big if we lose from our prediction and realizes that's a gambling which can gives us lose and wins.
