Djokovic missed the 2022 Australian Open and was deported from the country due to being unvaccinated against COVID-19 before returning this year to clinch a record-extending 10th title at Melbourne Park and 22nd major to reclaim the number one spot, Reuters reported.
He was forced out of big tournaments in the United States last year, including the U.S. Open, as he was unable to enter the country due to his refusal to take his shots.
The 35-year-old also received no points for winning the Wimbledon title due to the grasscourt Grand Slam being penalised for its decision to ban players from Russia and Belarus over Moscow's invasion of Ukraine.
"I think this is the least points I've had as number one. It happens," Djokovic told reporters following his win over Tomas Machac in Dubai on Tuesday.
"It's not only due to my circumstances of not playing a couple of Grand Slams and everything that happened last year, but also other players, some players missing some slams for injuries, some not having the biggest consistency.
"I guess that makes the achievement bigger, at least in my team's and my eyes. I'm overwhelmed with pride. I work as hard as anybody else. I'm really committed to the sport. And I try."
Djokovic is now into his 378th week as the world number one, surpassing Steffi Graf's record for the most weeks at the top of the sport.
The Serb first topped the rankings in July 2011 and has managed a best run of 122 consecutive weeks at the top, between July 2014 and November 2016.
But he said younger players like Carlos Alcaraz and Stefanos Tsitsipas will eventually catch up with him.
"These guys are playing at a high level constantly. They're playing a lot of tournaments. I'm not playing as much and don't plan to play as many weeks as they do," Djokovic said.
"Eventually they'll take the number one, then I'll bring it back again, then they'll take it again. We'll go in circles."
