Incorrect. First of all, no judge or jury ever renders a verdict of “innocent”. When a verdict is rendered, the defendant is either found guilty or not guilty, not “innocent”.
If a jury can’t agree on a verdict, there is no verdict of either guilty pr not guilty and what results is a “hung jury”. The prosecution may, legally, seek a new trial or it may drop the charges.
Until a person is convicted of a crime, from a legal perspective that person has not been found to have committed that crime. The public may “know” that that person actually committed the crime, but from a legal perspective that person is not guilty of that crime until a jury agrees that the prosecution has the met of proving beyond a reasonable doubt that the defendant committed the crime.
Where your analysis struggles is the meaning of the word “cleared”. The court system does not purport to “prove innocence”, which is implied in how you are using the word “cleared”. When charges or dropped or a not guilty verdict is rendered, all that has happened is that a decision was reached that the evidence that would be or was allowed in court would not likely or or did not meet the standard of proof required to reach a guilty verdict.
We do not live in a world, perhaps not even in Russia, where once a person is charged with a crime the defendant carries the burden of proving one’s innocence. It would be a terribly unjust world if it were so.
I may have video evidence that X shot Y but if that’s my only evidence that X shot Y and for whatever reason a judge suppresses that evidence from being submitted at trial, X walks a free man. You and I would be appalled, but in the eyes of the law that man is not guilty. He wasn’t “cleared” in the sense that the court affirmatively found it was not X who shot Y, but he was cleared in the sense that X was not convicted of that crime (there is often a plea agreement to other charges) and legally is a free man. The record will forever show that he was accused of a crime, but it will also show that he was not convicted of the crime, free to take a job at the local Starbucks or to play for a professional football club.
As for what each of us believes, that’s an entirely separate question and we are all free to believe what we wish based on what we have seen, heard or read.
