Addiction and professional job doesn't have to be separate things, you could have both of them at the same time. I mean your job could be your addiction as well. Not all addictions are bad addictions, people do not realize this but the meaning of addiction is doing something constantly and feeling terrible when you don't. So something as healthy as walking 30+ minutes a day could be an addiction if you feel horrible when you don't, like as in the day is ruined if you don't type of mentality means its addiction, doesn't have to be for a bad thing. If trading is an addiction to you, then you could be a terrible trader losing a lot of money or a professional one making a lot of money and we can both consider them addictions.
