No, I don't consider trading as gambling because gambling depends on luck mostly and trading depends on your skills and experience.Though trading needs a little bit luck but it doesn't not matter much rather gambling is just matters on luck.
you are right. difference of gambling and trading is in how you make money. on gambling, it was pure luck, while the trading is dependent on the skills and your experience, if you do not have it, then it all just depends on your luck
I will not believe that in gambling it is just a pure luck, you might not witness those who are successful in gambling in the long run and I am quite sure they are not relying on their luck alone as it cannot be with us all the time, maybe it is appropriate to say that gambling needs to be skillful to make money but if you are lucky you will increase your chance.
It depends which games they play, if they play dice rolls then it is luck only that made them rich, but if they play poker or even blackjack then they also needed skills
