The 18-year-old, who is from Blackwood, took home gold at Saturday's German Open in Hamburg, Germany.
Williams performend well and won the -67kg division taking an impressive 112 points from just four fights.
"At the Euros nobody really expected me to medal. I just tried my best but now there's added pressure to perform," Williams told BBC Wales Sport.
"The German Open was vital for me as I needed points to go to the Grand Prix. Winning gold really was a big bonus.
"I've medalled consistently at competitions. I feel I have to maintain that reputation and keep medalling at these competitions but I try to not think about it too much and put my best into everything.
"The high scorings make it more exciting. Being able to pull off matches with high scores is a massive bonus as it shows the kicks I'm throwing are working and it's given me confidence to throw high-scoring kicks."
Williams first considered taking up taekwondo after watching fellow Welsh fighter Jade Jones win gold at London 2012.
She now trains alongside Jones with the British squad in Manchester and says the double Olympic champion is a great inspiration.
"It's amazing to train with Jade herself. Jade and Bianca [Walkden] are both Olympic medallists," Williams continued.
"To be able to train with them everyday and really push myself gives me great confidence that when I do go out into the ring and fight, they're not going to be much better than Jade and Bianca, so it's a massive confidence boost
"My next big aim is the senior World Championships. I'm hoping to be selected for that. If I can medal at that competition it will put me in a really good place and make qualifying for the Olympics a bit more accomplishable."

His lawyer Brian Webber told the AFP news agency that a decision over his early release has been referred back to the parole board.
The Paralympic star was jailed for five years in 2014 for the culpable homicide of Reeva Steenkamp.
He has been fighting a lengthy battle to be released early from jail.
Pistorius was due to be released in August, but remained in prison after Justice Minister Michael Masutha made a last-minute intervention blocking it.
The parole review board - the final recourse for parole disputes - met on Monday to decide if the star, 28, should be allowed out on house arrest.
A definitive parole ruling is now unlikely to be made before the athlete in a separate legal process appeals against his conviction on 3 November in Bloemfontein.
This ruling could result in him receiving a longer prison term.
Mr Webber explained that the parole review board decided to refer the matter back to the original parole panel - the body accused by Mr Masutha of "prematurely" wanting to release him in August.
There will not be much sympathy for Pistorius because many people felt that the judge erred by acquitting him of murder.
The double amputee will have to remain behind bars because while his case joins the lengthy queue of other parole hearings that need to be heard, and there is no indication when this will happen.
Legal experts say the decision by the justice minister Michael Masutha to intervene was correct in terms of the law.
At the time of his intervention, Pistorius had been granted parole only six months into his five-year sentence.
The law states clearly that an offender can only be considered for parole after serving one-sixth of his sentence, in this case 10 months.
But because he has now served one-sixth of his sentence, he probably should be released by now.
Prosecutors argue that the judge who presided over his trial did not apply the law correctly by acquitting him of murder.
The judge instead found him guilty of a lesser charge of culpable homicide - equivalent to manslaughter.
Reeva Steenkamp's parents are strongly against Pistorius' possible release, telling an Australian TV channel in August that the Paralympian has ruined their lives.
"He killed her. He admits he killed her. She's dead. Why didn't he just let her walk away? Why?" Reeva's mother June Steenkamp asked in the interview.
European Taekwondo champion Lauren Williams says she feels under pressure to keep up her winning record.
