Trading and gambling are two different things, either with emotions or not, what you will have to understand is their differences and the risk as you've mentioned already, being emotional is what can lead to any of the trading experience or gambling but that doesn't mean they are thesame, if you trade you earn with a little probability of loosing small amount of money, if you gamble you're liable to loose the whole money, trading is an investment while gambling a liability as some may believed.
Gambling is an addiction on the other hand trading is like gambling but there is no fear in trading. Because there is very little chance of losing all the money by trading. But those who are addicted to gambling have a little more risk because all the money is at risk during gambling. I am a gambler. And trading finds many differences between the two so I think both have risks.
