I think Many serious gamblers use statistical analysis to inform their betting decisions, but not all gamblers use this method. Different gamblers have different approaches to betting, and many rely on intuition, gut feeling, or other strategies.Some gamblers may also use a combination of statistical analysis and other factors such as knowledge of the game, personal experience, or insider information. Betting preferences can also vary depending on the type of gambling activity, such as sports betting, casino gaming, or online poker.
