Trading and gambling are two different things. But you can be doing both things in the the financial markets. Gamblers can make a lot of money quickly but those trading properly probably won't. Good traders can make a living from it but generally their capital will grow slowly but surely. To make a lot of money very quickly you would need to 'gamble' and more often than not, these people tend to give back all or much of it if they haven't quit while they're ahead.
