Josh was up against returning player Paul Abrahamian and his closest pal Christmas Abbott in the Final 3, and after winning the last Head of Household competition, the Miami native decided to take Paul to the end, which was a very risky choice given Paul's strong resume of big moves, manipulation and competition wins.
Josh toldEntertainment Tonight after the live two-hour finale broadcast on CBS that he thought he had "no shot" to win Season 19 against a savvy player like Paul, 24-year-old clothing designer and band member from Tarzana, CA.
"Not at all," Josh confirmed. "I don't even know what's going on. I don't even think I won. It's crazy."
After 92 days in the Big Brother house, Josh, a 23-year-old in haircare sales who currently resides in Homestead, FL, took home the grand prize of $500,000 via a tight 5-4 jury vote over Paul.
"I was completely shocked," Josh told ET of the close jury vote, adding that Cody's vote blew him away since the pair pretty much hated each other during their time together in the house. "I was like, 'What?!'"
Cody reportedly said that he chose to vote for Josh to win because the loud and emotional houseguest had at least been honest to his face about not liking him.
As viewers saw on the show, Cody had no respect for Paul, especially after he felt the self-declared "puppetmaster" verbally disrespected his girlfriend Jessica Graf in the house.
"Wow, that's huge. That's awesome," Josh noted of Cody's decision.
Paul appeared crushed and devastated over the loss because he worked extremely hard this season and also finished Season 18 in second place behind winner Nicole Franzel.
When asked what he's going to do with the prize money, Josh replied, "Honestly, I have no idea."
"[Get] an accountant! An accountant, an accountant," he joked. "I have no idea. But I do know that me, Paul and Christmas, we planned to world tour. I'm going to stick to my word. We're going to travel the world together."
As expected, Josh also plans to "give back" to his parents. (He lives with his mother and multiple family members).
"They're like, 'We don't want anything,' but I want to give back to them," Josh confirmed.
Josh also insisted to ET that he'd love to play Big Brother again if granted the opportunity.
"Give me six months and I'll jump right back in, pot and pans and all!" he joked.
