I would like to try my luck and get a lottery ticket. How can I do it, what will be its cost? Tell me please

you can buy a lottery ticket (Ticket token) at the current exchange rate as
on the cryptocurrency exchange, and through the exchanger built into the decentralized application.
and now I have another question: if this lottery is not a typical business model, how is the game itself going? And how do I know how winning a ticket is from me?
