Are coincidences merely just coincidences?

It's really funny because I was scrolling through my yt feeds looking for some unfamiliar music. Then I stumbled upon this song called, "last of her kind." immediately a certain person popped in my head. Seemed interesting so I played it. The first line was, "it's been 17 days since you left." I paused it, wondering how long it has been since the last time I talked with that person in my mind. So I checked the screenshot of our last convo. It was sept. 21...
And it's now the 8th of october...

Fck! It has been 17 days. Like Wtf, as the song says,

IT HAS BEEN 17 DAYS!

Haha coincidences...
