OTOH, legal lotteries get a lot more people to gamble. I suspect that people who gamble either way gamble more as well, though this needs a fact check that I don't know how to find.
Probably, although Australia's lottery operator experimented (briefly I understand) with making their lottery and wagering products available through a single website/gateway - I don't think it lasted because while there was some overlap between lottery players and gamblers, it wasn't big, and I think while gamblers could be enticed to buy lottery tickets, it was much harder to entice lottery players to dabble in betting on horses or sports games.
