Everyone who is into gambling could've experienced winning and losing. It is part of gambling, and a strategy won't be successful all the time. We need to make changes and try. If we're lucky for the day, it'll turn out to be a win. If not, we end up losing. Based on my gambling experience, the number of wins was higher than the number of losses. However, when we calculate the statistics, most of the gamblers will be having a negative balance, whereas a very few number of gamblers will be having positive statistics.
