My grandfather is like that and he passed that behavior to my parents everytime they are betting on the lottery.
Nothing wrong with the habit and no effect on RNG. It's just that, that routine is good for others as their own way of attracting luck by sticking and being loyal to their picks as they believed their efforts will soon be rewarded.
That also applied to other picking number games.
I'm not really a fan of betting on a lottery but I do know people around me that used to bet on the same numbers that they inherited from their parents or they simply called "a well-care lottery number" of them. Well,I do believe that there's nothing wrong by doing such thing but I do only concern about how long would they wait to have a chance to win such huge price from lottery. I mean does the money that they could win in future could cover up their daily bet spent on lottery what exactly I mean is that if we would sum up the long time or the number of days multiplied by their daily bet on lottery does their lotto winning money is enough to covered the long time daily spending of a lottery bettors?
Honestly, the lottery habit is still running in my place which is dominated by elderly parents, while young people nowadays bet more at online casinos. And the most unique thing is that the grandparents created their own casino community. I will illustrate how they designed the casino.
Example: 10 parents collect money for a whole month each have to deposit $1 per day, so every month they collect 10 x $30 = $300.
And it should be noted that their casino still uses the conventional system, namely by taking the numbers that have been provided in large bottles at random and the number that comes out is the winner.
The funny thing is, when one parent wins, he will treat all his friends who bet and celebrate the victory.
