Of course, the main purpose of trading is to make a profit, that's why, day by day, we must learn more and more to optimize the profit. It's just that, indeed, all trading risks to losing money cannot be avoided, especially when we play in the Future market.
It's just that, regarding addiction, I think I have a hard time distinguishing it, is a professional trader addicted to trading every day? I don't think so, because no matter how they do it, sometimes as a job, they are used to trading and all its very complex analysis.
Then, maybe the difference with gambling is, when trading, usually someone will do their own analysis and calculations, whether the results will be loss or profit, but there should be their own analysis. If it turns out to be losing money because of the future market, I don't think it will lead to addiction, because it's too dizzy analyzing the market. While gambling has a sense of fun, right? That's why it makes you curious and still enjoy doing it, because often it's purely based on luck, just guessing.
