One common myth about card counting is that it guarantees players will win every time they use the technique, when in reality, it merely provides an advantage over the house rather than a foolproof strategy. Another misconception is that card counting is illegal; however, it's a legitimate strategy although casinos may ban players suspected of using it. Some people believe that card counting is incredibly complicated and only for mathematically gifted individuals, but in fact, basic card counting methods can be learned and used by anyone with practice.
