The 54-year-old former world heavyweight champion is due to fight for the first time in 15 years when he meets the four-division world champion, 51, at the Staples Center in Los Angeles.
"Iron Mike", speaking to boxing promoter Eddie Hearn on his BBC podcast "No Passion, No Point", said he did not want to think about where he would be without the sport.
The American, jailed in 1992 for rape, also paid tribute to his late trainer Cus D'Amato for giving him moral guidance.
"That kid is always in me," he said. "Now I know how to treat him, how to protect him. I wasn't protecting him when I was going to jail and all this crazy stuff. The best thing that can happen to any young man or woman is to have a diligent role model that cares about them. The feelings have to be mutual. Your objective has to be to make them happy -- to be the man they need you to be. Just think where I would be without boxing. I don't even want to think about where I would be without this beautiful sport."
Tyson terrorised the heavyweight division from 1986 to 1990 but he says becoming the youngest-ever world champion aged 20 came too early for him. Apart from his prison term he battled drugs and lost the fortune he earned in the ring.
"The best time of my life was probably right before I won the title," said Tyson. "When I won the title it got tricky. It wasn't the right time for me. I had too many emotional vampires around me."
Both men have rejected criticism that Saturday's pay-per-view bout, which will be staged over eight two-minute rounds, is a "circus act".
Tyson said he would bear no resemblance to the man who was beaten by Irish journeyman Kevin McBride in his last fight in Washington in 2005.
Jones's last fight came in 2018, with a unanimous decision over cruiserweight Scott Sigmon. Tyson predicted a full-blooded contest. "I think Roy can handle getting slapped around a little bit," he said. "It's going to be really hot in that kitchen."
Tyson has dabbled in films since he retired from the ring and says he is in a good place now. "I'm living responsibly, being present," he said. "That's what it's about for me now."
