It is this deteministic "Pool Billiard" view.
You are right for really large objects (marcocosmos)

But when going down to atomic level, the quantumeffects
prohibit to measure and predict the current and future states.

These effect get really small in large scale systems,
but are very valid for small systems.

So the probabilistics of quantumeffects will not change wheter a star will explode or not,
(the probabilistic behaviour of the thousands of atoms will even out to have any significan impact)
but they will decide, whether a Uranium-atom will fall appart now,
or in 1 hour.


So if you devcide your fate on whether a star will explode or not,
is a game of no chances, since you know the future.
(well if you had all information, but I mean there is only one possible future for the specific star)

Deciding your fate on whether a Geiger-Counter will click now or in 2 seconds
is a game of complete chance.
(cant be predicted for shure !)
