The two compatriots were locked together at five frames apiece at one stage before White - who made a century break at the age of nine to earn himself a place in the Guinness Book of Records - won five of the next six.
Williams had actually taken the first frame of the afternoon session in Sheffield to draw level, only for his opponent to then seize control of the match.
Breaks of 90 and 96 in the final two booked the 21-year-old from Neath a place in the second round, where he could meet 2012 semi-finalist Stephen Maguire.
"It means everything to me," White - who came through qualifying to make the main draw - said afterwards.
"I always looked up to Mark as a youngster growing up and it was a privilege to play him, and to play as well as I did means I'm over the moon."
Two-time champion Williams, who defeated Terry Griffiths in his first World Championship match 16 years ago, was full of praise for White.
"Talk about the young players coming through and he's one of the best of them," he said. "People keep mentioning Jack Lisowski and people like him. He's up with them, if not better."
There was to be no perfect start in Sheffield for another rising star of the game, however, as Jack Lisowski was beaten 10-3 by Barry Hawkins, who will next face either world number one Mark Selby or qualifier Matthew Selt.
The 21-year-old from Gloucestershire said: "It was just not meant to be this year. I learnt what the venue is like, that the crowd is really close, and your concentration has got to be 100 per cent or you can't really compete."
Meanwhile, Shaun Murphy opened his campaign with a 10-5 result against Martin Gould. The 2005 champion crucially took the 10th frame after 57 minutes to move 6-4 ahead and from then on moved clear.
Murphy managed a break of 106 in the 14th frame to move to the brink of victory and then was on course for a maximum in the next, managing eight reds and blacks before eventually running out of position.
