Sometimes, events we can not explain take effect, and there is nothing we can do about it, but rather we just ought to be very sensitive to allow things work accordingly. Things of this nature have happened in the past and people won good prices, and they also shared their experience and how they got to win games they never had in mind to play, but just for the fact that they felt like playing such games at that moment, they just do as they were led by their instinct, and they won good games.
This is how luck plays out. It gives you a big surprise of your life that people will be wondering how possible was it. Some will come up with different stories because they're jealous. The man and his wife luck worked together which made them win the lottery. Luck is all I need whenever, I'm gambling amd not skill or strategies.
To a great extent you are absolutely right bud, the place of luck in gambling can never be over-emphasized to be honest, luck in gambling is way more important than any type of gambling skill, strategy or knowledge because where all of this are present, if luck is absent, the gambler will still end up a loser, but a game where skill, strategy, knowledge is absent, and good luck is present, the gambler has a very high chance of emerging a winner.
Lottery for example isn't a game of strategy, it's not a game of skill, and it's not also a game of knowledge, it's a game where luck has to be present for any one whom luck points at to win, this is the same for slot and some casino games, the way luck shows up some times for some people is usually hard for the human mind to comprehend, and this story shared by the op is a very good example of such, even myself is still finding it hard to believe that this type of luck is ordinary.
