How does a lottery syndicate work? Why does it "increase" the chance of winning? - lottery syndicate

I know, gather a group of people and present their contributions and "get their chance" to increase, but, like mathematics?

I mean, if 1000 people is a union member, as it is more of a "utility" (as proposed by the unions), as compared to when each of them a ticket to buy for themselves?

Thank you.
