Winning in a jackpot is not a simple feat. it is like one in a million chance or probably more, so keep repeating it may give us more harm than good.
You have a point there, but in as much as such winnings as O.P proposed happens once in a million chance, how will you be able to win if you don't play once or twice a week with little money you can afford? because I will not advise anyone to gamble consistently all in the name to win a jackpot, because literally, such winning is always a result of luck to individuals who least expected such a huge shocking sum of money.
For those who doesnt really want to play on daily basis or often as they can even talking about small amounts then most of the time they would be falling down in to the category of playing lotteries.
This is always been the best option or nearest thing that they could think off on how to win millions on having less or not so big amount to be spent on tickets and this is why we do see about those
bettors on particular lotteries.
On the other hand, if we do talk about slot jackpots and even hitting jackpot pots on dice games or other then it would really be needing the other way around.
