Randomness doesn't exist. @Kieran is correct.
Every possible outcome of a quantum mechanical state "evolves continuously and deterministically" in some universe, so every universe is deterministic.
Instead of thinking about random events, it helps me to think about some events as being inherently unpredictable. I replace the word "random" with "unpredictable".
Every possible thing happens to me in some universe, but I can't know which universe I am in and where I am going.
From my perspective some things seem inherently random, but it is just me not being able to know which universe I am in.
If Schrodinger's Cat ever seemed mysterious or unsatisfying to you, this is the solution. The cat isn't in some weird "superposition" of dead and alive at the same time in the box. The cat is actually either dead or alive in there, but until you open the box, you don't and can't know if you are in one of the "cat is dead" universes or you are in one of the "cat is alive" universes.
If you want to understand this better, drop this paper in your favorite LLM, and have a discussion about it.
