And if compared to trading then the only difference is that trading can be predicted but not with 100% accuracy, while in gambling everything cannot be known and cannot be learned and that is why gambling is called a lucky activity and trading is called a skill activity that is quite dependent on one's knowledge.
In both gambling and trading, you can predict them and you might not really be so accurate but before you can make profit in trading, you actually need skill and not luck. Like you said above, which I also said before now, gambling is based on luck and it doesn't matter if you are gambling repeatedly, if the luck is on your side, you are going to win no matter the losing streak you have already had in the past minutes.
