Not always. Some are well funded. Others the rich kids from the nice neighborhood go to private schools, so the rich parents don't care about public school funding. Often poor parents don't care about school other than a cheap daycare and so they don't fund the public schools well either.
Note that school funding and outcome is not well correlated.

I think that’s a bit of an unfair characterisation. Most parents do want their children to have good educations.
Without having any source or data to back up this claim, I would expect that the difficulties faced by poorly funded schools full of poor pupils are not due to parents not caring about the schools or their children.
If you look at school districts that have more than one school: the schools in poor neighborhoods have worse results than the ones in middle class neighborhood. This is within the same school district so school funding is the same.
It is fair to say I don't know the parents don't care. However whatever the difference is, it is at home not the school.
