The story is truly a rare coincidence. Where the small, simple decisions of refusing the man's wife's bottle of juice, taking back the man's money for the juice, and using that money to buy a lottery ticket all come together to create an incredible result. Those small, coincidental actions are given a lot of importance in the context of winning the lottery, but if he hadn't won the lottery, he might never have noticed them.
Yeah, it is a real coincidence. The same goes when we're stopped by traffic and there is something that's about to happen in front of the traffic and that's why we're delayed.
It's fate and there is no real reason why they'd done that and some intergalactic connection that people are imagining through it.
These simple matters just creates something that we have to talk about and that's why we think of it that much on how it happened.
