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.
That depends from your point of view on this but both are risky and need luck in some point. When you gamble or trade goal is same want to gain income so in some point this is matter of opinio on this someone will say they are same other that is not.
