I agree, but I don't want to say "zero".
While fishtank/Sam Hyde was unironically the best and most significant chance that he ever stood of having his current reality broken and improving himself... that is only so far.
If he is extremely lucky in life and comes across the "right people" he may find an environment in which he comes out of it and improves his personal circumstances, but coming across the "right people" in the first place is basically never, ever going to happen and broken people like Alex tend to attract either even more broken people or extremely exploitive people like the ogre. Given the grasp that the ogre has on his life currently, its extremely unlikely he'll ever come across the "right people" in the first place and even if the ogre goes away by some miracle, she will probably just be replaced by someone or something else that fills the place of the ogre (and she's pretty fucking big, so many it will be several people)
