Well we dont know who you are going to communicate this to in person. (Dont say!)I'd look for a clear contrast in your own mind between gambling as an enjoyable hobby, and trading say financial futures for a commercial and profit motivated purpose. Its fairly normal to show a real interest in a career path, and neither activity need lack legitimacy in the UK. New entrants often use the hobby section like this.Personally I reckon that blurring the old ethical divides between gambling and trading makes it more necessary to communicate this quite clearly though. People might not care themselves, but gambling and trading are not really the same. I'd suggest that there are significant contrasts.The context is usually very different, so if it was put forward clearly I'd see it as a small plus or a possible talking point. Others might be more cynical.
