Well of course not, in trading you are 100% sure that you will get something, even if less than you bought for, while in gambling you can't be 100% sure that you will get something back, so trading is not even close to gambling.
That is not completely accurate if whatever you were trading crashed down to zero you will not obtain anything out of it.
Yeah I think you are right, because all I know when you trade you will be the one who check if the trading is coming up or coming down and this will need more patient. You need to wait until your money grows up. You must also know what should need to buy or sell. We all need knowledge before we enter trading.
