I am talking hundreds of thousands of dollars of lottery tickets per week. Their winning are also along those lines. I don't know about the industry, but these sound like professional lottery players who check odds and play the system much as they would the stock market. They probably have set systems in place and complex prediction and statistical algorithms which ensures they win just more than they lose?
I am thinking that 'pro' players such as these might skew the statistic for winners to a large extent?
