Why is a state's supreme court often called the "court of last resort"?

The Supreme Court of a state is called the "court of last resort for a few important reasons."
One of them is not because it rhymes.
If there's a court discussion and the verdict of the judge seems to have legal flaws, the person who would get charged by the decision of the judge can file an "appeal."
It would then get moved to a higher court.
However, here's the problem. Judges can make contradictory decisions that completely oppose the verdict of the previous judge.
That's where the court of last resort comes in.
This court has the undisputed highest authority in the state.
Their word is the final verdict.
However, there's still the supreme court, but there's really no assurance there.
They hear very few cases, and unless yours is very important, it's not likely yours will be chosen.
Hope this helps
