Can my neighbors husband really get paroled for the first time in tennessee

Wreckless endangerment involving a deadly weapon and second degree murder. Sentence end date is March 2032. She says he knows the sheriff really well and hasn't gotten in trouble and it almost guaranteed parole the first time. He is also still in county jail. What are the chances he gets paroled the first time he is serving it in Tennessee. She says because they have 5 kids he is guaranteed parole. Is this true or is she delusional?
