I think it's a bit more complicated than you make it sound. I live in California, so of course all my state's electoral votes went to Harris. I could have not bothered to vote, but the problem is that if everyone like me were to think the same way, those electoral votes could go to someone else.
So yes, in a literal, technical sense, my vote counted. But in reality, my vote had little to do with the outcome, whereas the votes of someone in Pennsylvania or Arizona had everything to do with the outcome. Those seven states absolutely did decide the election.
I do think that tallying the overall popular vote is a useful metric, even if the election's outcome doesn't depend on it, so I guess in that sense my vote "counted" as well.
