The three-times world champion looked forward to returning to the Crucible next year and promised to outdo himself if he defended his title. "I had to wear the towel on the orders of [world snooker chairman] Barry Hearn otherwise I would just have walked in, just crying".
The 18-16 success made him the oldest victor at the Crucible since 45-year-old Ray Reardon in 1978 and Williams fulfilled a promise to hold his press conference naked - although he wore a towel to protect his modesty.
Almost true to his world - he later disclosed that Barry Hearn ordered him to wear the towel - Williams strolled to the media room with some interesting tattoos on show.
Reardon, the man nicknamed "Dracula", was 45 when he won in 1978, and while Williams is 43, no one would now bet against either the Welshman or 42-year-old Higgins winning again in years to come to beat the record.
Welshman Williams, 10-7 ahead overnight, led 14-7 and then 15-10 before four-times champion Higgins, a beaten finalist past year, rattled off five successive frames to level at 15-15.
And Williams has already made his promise, should he retain his title next year.

Glover is expected to drop his as-yet-untitled album in the near-future, and holy christ, do we have exceedingly high hopes. Glover has been the focus of much of the marketing material thus far, resplendent in a variety of funky outfits.
I don't know enough about snooker to interpret for you the circumstances or specifics of the game that lead to his victory in a way that wouldn't sound incredibly forced and likely very incorrect but, I can assure you, he sure hit those balls better than the other guy, then he got naked. The antics did not just end here, Williams has now vowed to perform naked cartwheels if he repeats his stunning triumph next year.
"I'm over the moon - what a match to be involved in", said Williams. 'I'd expect to make that 48 times out of 50.
"12 months ago I wasn't even here".
Williams said: "It's unbelievable". Higgins was beaten, but he had played his part in one of the greatest Crucible finals. The Welshman, however, held his nerve in the next frame, a break of 69 taking him over the line.
"Although I had an unbelievable amount of respect for Jimmy White as a player, for him to come back six times, lose six finals and still be a class act on and off the table", he said.
"I just can't believe it".
