It is technically possible to make a living solely from online gambling, as there are professional gamblers who have been successful in doing so. However, it is important to note that online gambling is risky and unpredictable, and the vast majority of people who attempt to make a living from it ultimately do not succeed. It requires a high level of skill, discipline, and a deep understanding of the games being played. Additionally, there are legal and ethical considerations to take into account when considering a career in online gambling. Overall, while it is possible, it is not a reliable or sustainable way to make a living for most people.
