Is Tom Sawyer a real person in Huckleberry Finn?

Excuse me, but I have a question regarding the literary work "Huckleberry Finn". I'm curious to know if Tom Sawyer, the character mentioned in the novel, is based on a real person or if he's purely a figment of the author's imagination? It's a fascinating aspect of literature to ponder, the intersection of fact and fiction, especially in classic novels like this one. Could you please enlighten me on this matter?
