At the microscopic (atoms), mesoscopic (macromolecules) and macroscopic ('human') levels, the Universe seems to be under the influence of random processes (radioactive desintegration, DNA mutations, dice rolls; gouldian contingency);
At the megascopic level, however, the Universe seems to be under the influence of regular mechanisms (half-life of radioactive elements, molecular clock, mathematical laws; in short: natural laws).
In a way, ot could be said that random processes correspond to misleading appearances, whereas more general, regular mechanisms reveal the deep nature of the Universe.
The conclusion of this reasoning is that our Universe would be fundamentally deterministic.
As deterministic, I mean that ‘everything is linked’, ‘everything happens for a reason’. "Determinism here refers to the idea that the future is dependent upon the present such that, given the present, only one possible future exists" (https://dictionary.cambridge.org/fr/dictionnaire/anglais/determinism).
In other words, I refer to "the philosophical belief that all events are determined completely by previously existing causes" ( https://en.wikipedia.org/wiki/Determinism).
In short: no chance, no contingency: only inevitabilities.
It is helpful to think of quantum theory as an empirical probabilistic theory as Schrodinger suggested, that uses empirical form factors and many constants, rather than it being a physical theory. Physical classical theories, with no new math, which explain the underlying physics, do exist. [i.e., see link]

Actually in both the biological field (Jaques Monod) and in physics the world is a combination of both determinism and contingency.
I have also read about parallel universes somewhere. I think these are universes with different initial conditions.
And: what are random processes?
Random process is a process the reason of which we cannot or we do not want to tell. So the death or birth of a star can be a random process, or the global warming is also that. The result of a casino game happens also by chance.
And what about the ghost of Laplace?
It is impossible.
