Are there many people using the 26 key or the 9 key?

I am a 9-key player. Personally, I think those who use 9 keys are all played by keyboard players, while those who use 26 keys are mostly students. (Of course, many people around me also use the 9 key. I am a sophomore. People who use 9 keys generally think that chatting is good and typing is fast. Because the input method makes nine keys particularly easy to produce associative vocabulary. The advantage of the 26-key should be its accuracy. Of course, it's up to you to type fast or not.
