the seniors probably have those superstitious belief. there were people who sometimes hear something on TV or combine the birth dates of their children to bet on lottery. people are hopeful to get the instant money but there are times where there are multiple winners in our lottery, it must be true and not rigged.
i'm not sure if there is a trick to it that the city can program numbers to come out but in my country we use the Air-Mix Lottery Machine where numbers are on table tennis balls.
Not just seniors but even the young adults these days are also being influenced by those beliefs that even myself can't easily get out. But in times i also bet on random numbers just to try my luck, and most of the time i lose. However, i don't know if there are really tricks about it but if there may be, i guess some lucky players might have obtained it.
