Does Luck Exist?

Luck

I always think or I should say I always believe one thing.....
That fortune always comes with a reason.
Always.

Let's see....For example,

One day, you are homeless with nothing but a pair of clothes in your body and you are starving to death.
But at that moment you found a piece of delicious bread came out of only God knows where.
So you ate it without even thinking because you were hungry.
And then you survived,of course lol.

Aren't you so lucky?
That's what everyone thinks that they are so lucky.
But are they really that lucky?
What's the reason behind that fortune?
After thinking a lot I came up with a conclusion.
According to me if God exists then.
The reason is,

God doesn't want you to die yet.

Maybe hell is full,so he delays your death and makes you struggle to live a little bit longer.
