Op nothing is actually impossible on earth, but just know that gambling is a game of luck and seeing it as a profession or career is more or less being jobless because no one can actually accommodate risk as an occupation.

career here stands for something that you will be doing to earn a living and cater for yourself and your family if am not mistaken, and seeing gambling here as a carer there are some likely factors one had to consider before taking such decisions which include the following:
1. gambling is not certain; any person or group of persons that want to see gambling as their source of livelihood should put at their minds that gambling is not certain rather it is based or probability(an outcome of an expectation in any numeric event) either to win or loss.

2. gambling has no basic salary wage: this is factually another important factor that the person has to consider because there is no specified salary for gamblers rather, they earn through predictions which your predictions might fail you as well ( still revolves in uncertainty).

3.you are responsible for your own liability : No company or firm will deem it necessary to employ a gambler as a staff ,however you can employ yourself and you are vitually liable for your own loss . no ones owes you any explanation for your loss and you also owe no one any explanation for your loss as well which invariably implies that you are responsilbe for your own liablilty .

4. lastly in gambling you dont report to anyone instead you report to your emotion and conscience and many more other things to consider .However , for me it is not ideal for someone to see gambling as a career or a profession beacuse it lies in a two sided efforts is either you loose or you gain.
