Woods finished second at Bellerive in the final major of the year to show that he is back in the business of challenging for the top prizes in golf.
His final round of 64 left him just two shots behind winner Brooks Koepka, who ends the year with two major titles.
And Thomas opened up on the Woods factor returning to golf.
“I had a par putt on 17 on Sunday, about a 5-footer,” Thomas said of the final round.
“At that point, I didn’t really have a chance to win.
“I made the putt and I’m walking off the green and everyone just went nuts.
“I’m like, ‘That’s weird. Why are they going so crazy?’ I turned around and they put Tiger making another birdie up on the scoreboard.”
Woods and Thomas will play together during the Ryder Cup with the former almost guaranteed to be one of Jim Furyk’s picks.
Thomas, 25, is ranked third in the world behind just Koepka and Dustin Johnson.
“I’ve played a bunch with Tiger but I’ve never competed in a major with him so that was something new for me,” Thomas said last week on the Stephen A Smith show.
“It’s unbelievable. The roars that you would hear throughout the course. The roars that you would hear just from his score getting changed on the scoreboard is… unless you truly experience it, it’s pretty unbelievable.
“I know he’s obviously happy but we’re all happy to see him healthy and back because it’s good for the game of golf.”
He added: “I truly don’t think you can put anybody in the same boat as Tiger Woods.
“You can’t put into words what he is to the game of golf. It’s unbelievable… the amount of people that go out to tournaments because he’s playing.
“The opportunity we have is the kids growing up never watched the Tiger Woods that we watched growing up so we have the opportunity to be that player, that guy the kids look up and to me that’s a huge deal.
“I want to be a great role model to kids, I want to be someone they look up to, someone they want to model their game after kind of like I did with Tiger.”
