Of course you should not consider it as a game since it involves money and there is a chance that you will use your money, some people consider it as a gambling too since you need to deposit some money before you can trade and have profit. We shouldn't also consider trading as a game since it is not really a game but honestly trading is fun but we should know that just like gambling it is not always winning there are chances that you will lose trades.

It depends on people what their perspective about trading some people consider it investment, gambling or just simply trading.
