I used to think so, Or lets say that gambling and trading has a big difference. Gambling is no sure about money back while trading is sure in that case. Gambling is a game where you have no sure wheather you win or not. So absulotely, gambling and trading are not the same.
Trading wont make also sure to get your money back since the risk on losing money is always there too and we know trading isnt an easy thing to learn which is opposite on gambling which we can easily play it without any hardships but when we are seeing for long term profits trading does really have the edge.
