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.
^I have watched a live video before in my local about the lottery result before they will start, they seem weighing the ball and making sure it is the same size and the same weight. I don't know if there is a trick either because they doing it live and how many people have viewed and watched during the raffle draw. Superstitious belief is very normal everywhere in gambling, it could be people use this to place a bet in the lottery and buy tickets. Which is I think that how a percentage of winning do we have because the reason why people did not stay is just because of the chances of winning.
