"God doesn't exist" is just shorthand for "I believe God doesn't exist" and that doesn't specify how strongly I believe it. If I believe God is 99.99999999% improbable that is still believing to an extent that God doesn't exist.
There's all this talk about how agnostic atheists don't believe there is no God they just don't have a belief that there is one. This is true if they put no probability on the matter whatsoever. But if you believe it's far more likely that God doesn't exist than does then you do to a certain degree of probability believe there is no God. The thing is, the complexity and unfalsifiability and complete lack of evidence is indeed a very good reason to believe that God is highly improbable and almost certainly doesn't exist.
And in fact many definitions of God are actually logically contradictory and can't exist. For example, a definition of "God" where God is outside of the universe but the universe is the totality of everything. God cannot be outside the totality of everything because that's a logical impossibility therefore that definition of God cannot exist.
Another example is a God that has contra-causal free will when contra-causal free will is logically incoherent. God cannot change the future that he already knows and if he is said to be able to then that's a logical contradiction, once again, it makes God like a square circle.
I'm inclined to believe that many definitions of God are complete non-concepts. There cannot be a God that is outside of spare and time because everything has to begin to exist to exist, there is no time before time or space outside space because that's logically incoherent. The universe is natural, the whole idea of outside of the universe makes no sense. Supernaturalness makes no sense.
