Almost every speed hacker that is faster than other players uses the excuse "My laptop/PC is fast and good this is why im faster than others"
Is it true than a good PC make players faster than others? I'm not talking about smoothness, I'm talking about literally being faster so for example if you both raced the player will reach the end point before you do.
No, having a better pc won't make you move faster. Your client may freeze less on a better computer, so I suppose you could win a race if the other person's client stuttered or something - but I don't think that is what you mean.
