The Dutchman was eliminated from the competition after a 3-1 loss but made history with the nine-darter, winning £60,000 in the process - alongside a donation of the same amount to Prostate Cancer UK and for one member of the crowd at Alexandra Palace.
"The nine-darter was an amazing moment, hitting the double 12 felt amazing," Kist said.
"It was a lovely moment for everyone and I hope Kris (the crowd member) enjoys the money.
"Maybe I will go on vacation next month with the prize money.
"I lost the game though so I'm a little bit disappointed to go out in the first round."
Razma threw fewer 180s (five) and averaged less (90.65) than his opponent but still emerged victorious, winning the final three sets to seal his spot in the second round.
The Latvian will face Dirk van Duijvenbode in the next stage of the tournament.
