Also it is easy to gather money from gamblers from lotteries as most of the lotteries require less capital and give high returns.
Due to this, gamblers tend to take the risk and hope they could win a big jackpot by investing very little capital amount.
Sorry I think lottery is not easy to be won because it is highly manipulated. It is not like any blockchain games. The outcome of lottery is biase because of the non transparent manner it is organised. Although they are designed for high returns which makes players to move into it in numbers but they are just consistent losers in lottery and few lucky winners that are looked as compensation.
