Personally, I see a professional as someone who can consistently profit from their gambling activities. They are able to transform gambling, which many people consider challenging and uncertain, into a profitable venture, using their strategies. However, not all gamblers can be categorized as professionals, as those who focus on slots or games based on luck can't consistently make money. However, sports bettors or poker players can be considered in this category. And their approach is more structured, especially when it comes to money and risk management.
