Do probabilities actually exist? Like if I say there is a 50%

In a deterministic universe there technically is no probability. It's only what we are unable to measure. Our current interpretation of QM does give probability and non-determinism as a property of the universe. However quantum events rarely affect anything we want to measure, like weather. Your weather prediction is based on imperfect measurements so it needs error factored in.

Every event has a 50% chance of occurring. Either it happens or it does not. :)

don't they fundamentally affect EVERYTHING on every scale?

That means you don't know whether it will rain or not, and if you were to guess 100 time, you'd be correct 50.

No. Each particle is like a dice roll. When you roll trillions of dice, you can be very confident in the probability distribution.

This means that there is a 50% chance that an event has a 50% chance of happening and a 50% chance of not happening.

Then what is the other 50%?????

When asking whether a mathematical idea we use to describe aspects of reality really does exist, the answer is always no. Mathematics are an abstract concept, they can only exist as such.

So that means there's a 50% chance of me dying tomorrow?

You can't prove that so its not science.
