I think many gamblers are not aware of the concept of house edge or how it affects their chances of winning or losing in a particular game. This is especially true for casual or recreational gamblers who are simply looking to have fun and do not bother with the calculation of house edge. However, professional or experienced gamblers often pay close attention to the house edge and seek out games that offer the lowest possible edge. The understanding of house edge is an important consideration for serious and professional gamblers to increase their chances of winning over the long term.
