The statistical chance using our current models and understanding.
We have never observed such a large amount of atoms dispersing through quantum effects simultaneously. There may be some process we are unaware of preventing this.
Which is to say, there is a non-zero chance the chance of this scenario is exactly zero.
The satistical chances of every single atom in your body just randomly dispersing and you vanishing is not 0. Just a very, very small percentage.
The statistical chances of only a spot on your body doing that is near infinitely more likely than the first scenario tho.
