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.
There are many differences between trading and gambling. People get addicted to gambling but people never get addicted to trading. It is good to be interested in everything but it is never good to be addicted to anything. Both trading and gambling are risky but when compared to both, the risk in gambling is much higher. Gambling is either your money comes or your money goes. People lose thousands of dollars in a moment on all these gambling platforms but in trading there is no chance of losing money completely like gambling. Trading may show you temporary losses and make you wait but never lose your money completely so I think trading is a bit safer than gambling.
