The 18-year-old winger has enjoyed an encouraging start to the season at Anfield and is now with the England squad preparing for Thursday's Nations League meeting with Croatia.
Ngumoha has made no secret of his ambitions, taking inspiration from Harry Kane, who recently became only the fifth Englishman to win the Ballon d'Or.
The Liverpool youngster believes Kane's achievement can encourage more English players to aim for the game's highest individual honour.
"Yeah, 100%," Ngumoha said when asked whether he wanted to win the award himself.
"Harry Kane winning the Ballon d'Or is definitely a big, big thing, being known as the best player in the world.
"It's also helped English football now because everyone's seen one of us win the Ballon d'Or, it is definitely encouraging many more people to wanting to definitely be known as the best player in the world. For me, I would like to achieve it and I think I can do it."
Ngumoha believes having ambitious goals is an important part of becoming a successful footballer and has always backed himself to reach the highest level.
"I feel like if you don't visualise anything or you don't dream big enough, then you might not ever achieve it. So I think just having the belief and the force in your mind thinking, one day I can play for England.
"I think you definitely need to have that so you can drive to achieve it. So yeah, I've definitely always believed in it."
His confidence has been supported by his family, particularly his older brother James, who recognised his ability from an early age and now works as his agent.
"My brother (James) has been a massive part of my journey. He saw the talent in me from when I was like five years old, which is crazy to say.
"But yeah, he's my agent as well now. He just wants the best for me, and he's really supportive.
"My brother is tough, sometimes. I definitely needed that when I was younger. My mum has done a lot for me. The hardest thing for her has been moving up to Liverpool. She left her job to come move up. She does everything for me and my brother. She's just amazing."
Ngumoha previously spent time at West Ham United and Arsenal before joining Chelsea's academy at the age of eight. He eventually left Stamford Bridge for Liverpool in 2024, believing the move offered a clearer route into senior football.
The decision has already brought considerable rewards, with the teenager making 44 appearances for Liverpool and becoming a popular figure among supporters.
He believes the plan presented by the Merseyside club made the choice straightforward.
"I feel like I needed a new challenge. I feel like if I stayed at Chelsea - not saying that I wouldn't have got to the first team as quick, because I believe in my ability, but I feel like Liverpool just gave me a new pathway. The plan that they set for me was straightforward really.
"For me, it was a no-brainer going to Liverpool, and they just said if I prove myself, because they know how much ability I had, then they know that I would definitely be a first-team player and definitely a star for them in the making.
"I think going to Liverpool so far has been the right choice."
The winger has also earned opportunities with England and could be in contention for a more prominent role during the international break, with Bukayo Saka unavailable through injury.
Ngumoha recognises that competition for places is fierce but wants to make the most of any opportunity to impress head coach Thomas Tuchel.
"I'm competing with the best players in the world, so it's not going to be easy," he said.
"But if I can show myself in training and if the manager gives like faith and believes in me, then I'd love to start. But obviously, it's difficult, and I just keep going really."
For now, his immediate task is to continue making progress at Liverpool and establish himself in the England set-up. His ambitions, however, extend far beyond earning a starting place: Ngumoha believes he can one day become the best player in the world.
