Does luck exist?

[Gynn Rei]

As far as I know there is a mechanism that keeps the balls moving.
Also as far as I know, the motion of the balls is fairly complex, with ricochets and rebounds, plus there is that thing that seemingly plucks the balls out of midair for the ball selection. It's mostly coincidental that someone has the matching numbers on their lottery ticket.

On topic: Three words to disprove luck.
1) Physics
2) Irony
3) Coincidence

It's so complex that it can't be calculated... therefore it must be plain luck because the creators of the machine can't know what comes out.
