Prediction can sometimes favor you or fail you, because trading is also a game of luck and there's no one person that is perfect in prediction, just that when you are favored, it looks like you're the champion but I tell you that no champions forever.
Yes failure is never final, it's actually the key for improvement and learning. That's true but consistency can make you profitable in trading, as you can see some strategies success rate is 40%-60% and you can utilize the leverage in order to have a better profit in your position, so even if you managed to lose around 3-4x consecutive you'll be able to recover using leverage with the 40%-60% success rate of your trading strategy. I lose a lot of times before because I used the leverage the wrong way, and that experience taught me the importance of discipline and risk control.
I think it was Rafael Nadal, or some other tennis player, I don't remember who it was. That talked about how he won just barely 50% of the hands he played, which means, even the greatest ones got a little over half of the points he played all his career, and won so many cups.
That also means, he lost just a bit under half of his points, so he loses all the time and constantly, points of course not games, he did lose a lot of games too.
So you can't have full wins, all the time, that makes no sense and nobody can do that. If you are that level at trading, then you should be fine, and you can make some profit.
It would not be simple, and it would not be that bad, but it can happen and we are going to end up wit ha good return.
