There are event you can predict on that even though it's not 💯 guaranteed that you're going to win, a level of certainty makes you think that you're surely going to win.
The downside of that feeling is that you might become over confident to use a big amount in the game since you're to a large extent certain that you're going to win.
Can we still say we are gambling if the event is something we are at least 90% sure that we are going to win?
We are still gambling in this case, but I can argue this always with you that we can be confident in playing a game that it will be sure as a win, if gamblers already knows a particular game they can be having free chance ls of winning each time they are playing, then they will not stop from playing such each time they are gambling, we can't be rest assured in developing confidence on gambling, because it will be that we lose or win regardless of the game being played and there's no one that can blast of having it come as it has been presumed.
