Like he's done all year, Ricciardo took advantage of Mercedes' troubles after championship leader Nico Rosberg crashed into teammate Lewis Hamilton on the second lap.
His victory moved him to within just 64 points of Rosberg and 35 points adrift of Hamilton.
With seven races left and double points on offer at the season finale in Abu Dhabi, Ricciardo isn't ruling out the possibility of stealing the crown from Mercedes' grasp.
"If I'm within 50 (points) coming into Abu Dhabi then yeah (there's a chance), but there's still a few races to go," he said.
"While it's still mathematically possible, we'll keep fighting.
"Today was a big day for that. To come and steal some points on a circuit where, let's say, we weren't supposed to, is nice. It'll keep us smiling for a while.
"But I think what's important, looking ahead, is to capitalise on the circuits that we should be strong on and if we can take maximum points at a couple of those then it's never over."

The 25-year-old predicted "good things ahead" for his team, especially in Singapore and Japan after next month's Italian Grand Prix at Monza.
"We're really motivated right now," he said.
"Monza we know will be tricky again, but obviously the package we brought here was pretty racy, so, try and take something from here to Monza and then I think Singapore and Suzuka will be pretty good for us."
Ricciardo this year has completely outshone his four-time world champion teammate Sebastian Vettel, who's yet to win a race and only featured on the podium twice. He is a staggering 58 points behind the Perth-born driver in sixth on the overall standings.
"Let's say the in-team battle has gone really well," Ricciardo smiled.
"Obviously I've shown speed throughout qualifying and also races now.
"I've demonstrated good racecraft and good consistency, so I think the team has been really pleased and I've been pleased so we're in a good place.
"I'm enjoying it more than ever."
