For Zhao, who will face compatriot and fellow giant killer Lei Peifan next, it is a road to redemption after the 28-year-old served a 20-month ban for breaching betting regulations.
As a result he is playing as an amateur in Sheffield, although he will return to the professional circuit next season.
Lei beat 2024 champion Kyren Wilson on Saturday but Jones believes Zhao can go all the way and secure a historic success as he bids to become the first amateur and Chinese world champion.
“I don’t see anyone who is playing better than him,” said Jones.
“If he wins it, I wouldn’t be surprised at all and that would be good for the game.”
“There are players who have won a lot more, but I don’t see anyone in the tournament who is actually better than him,” added the 31-year-old Welshman.
Although Jones won the first two frames of the session – including a century break – to close the gap to 7-4, Zhao rallied and rattled off the next three frames to seal his place in the next round.
Zhao’s victory means there will be at least four Chinese players in the last 16 – a record.
Zhao said having to battle through four qualifying rounds to earn the right to play in the main event had shaken off some of the rustiness he felt through a lack of big tournament play.
“Overall I’m pleased with my performance, especially in terms of scoring,” said Zhao.
“This match was about regaining confidence.
“I won’t be back on tour until next season, so every match I play now is very important.
“I haven’t had many opportunities to compete this season, so whatever the outcome, I just wanted to do my best and show my game.”
Zhao, who also reached the last 16 in 2022, is taking nothing for granted against Lei. Their match is spread over three days beginning on Friday.
“Lei has played brilliantly and has shown he’s capable of winning titles,” said Zhao.
Three more Chinese players are in action later on Monday.
