I also know it to be a lotto machine and I have seen people predict or place bets on it but sometimes I ask myself how they get the money or where does the win come from when they get the numbers correctly, are there registered lotto companies like online sportsbook and Casinos? It's puzzling to me.
At a point I asked this kind of questions too but I got some little explanation from players at that time.
So winners get paid just like it is with known betting shops or casinos, online banking / wallet or physically. When they newly started, payment was through their kiosk and physically. For example if you win, you can present your ticket to any accredited physical kiosk/agent who will scan the ticket to confirm you won and how much you won. After that, you get paid the amount if it is available but if the amount is not available, you can be referred to another kiosk who has such amount of money. FYI, the agents sign out such money from the branches and they account for it using the numbers of won and scanned tickets from customers.
where does the win come from when they get the numbers correctly,
It is like lotto game. The numbers that becomes the winning numbers are drawn from machine like raffle depending on the time frame of the day, like morning, afternoon, evening games and I heard they have different names too. I can't remember them now.
