Possible to reach 130 WPM without using all fingers?!??!!?

HELLO recently I reached 122 wpm just using my pointer fingers. My goal is to get to 130 within the next week but I don't know if I should continue the way I'm doing it now, or try to learn to use all of my fingers. There's someone on here who can type over 200 wpm and KNOWING HE CAN DO THAT MAKES ME WANT TO BE ABLE TO DO IT TOO
