The rules are available to everyone, but having enough cash to purchase that many lottery tickets certainly isn't. Unfortunately this is yet another system that enables the already rich to get richer on the backs of the poor.
It’s hard to be sympathetic to people that make bad decisions as a habit. For example, if it’s a 1/5,000,000 chance of winning and they still keep playing, that’s on them. The have very little sympathy for losing lottery players. If people choose to spend their money like that, that’s their business, but that doesn’t invite sympathy when it doesn’t work out. It isn’t like they are being defrauded or even cheated. They have access to the same rules of the game and they have access to math just like everyone else.
I agree, and indeed this is a good argument for prohibiting lotteries. They're a form of predatory gambling that relies largely upon irrationality, addiction, and desperation.
