The 43-year-old climbed six spots to sixth after a one-shot victory at Augusta National which crowned one of the greatest comeback stories in sport with a first major title since the 2008 US Open.
Adducci was presented with a check on Monday for US$1.28 million, representing the payoff plus his original US$85,000 stake.
"Pretty good first bet", Nick Bogdanovich, William Hill's USA director of trading, told ESPN.
Reportedly Adducci's wife wasn't initially keen on the bet.
"She said to me, "I can't stop you from doing this, because if he wins, I'll never forgive myself".
"Prior to this comeback, the only thing my kids knew was that golf caused me a lot of pain".
Woods increased his total of Masters wins to five and boosted his major-championship tally to 15. Woods won the 2019 Masters on Sunday, ending his 11-year major-championship drought and earning renewed acclaim from around the sports world to the halls of political power and beyond.
When Adducci ran the idea of the bet by his father, the elder Adducci wasn't thrilled with the prospect.
Adducci said watching the tournament play out was an emotional roller coaster. Two other casinos rejected his wager. "I just wanted to do what I wanted to do", he said.
"Having met James, I couldn't be happier", Asher said.
James Adducci, 39, was a first-time sports bettor who day-tripped the 2 900km from Wisconsin to Las Vegas to place the bet at William Hill - and then promptly flew straight back home.
