When someone says Bitcoin is not crypto, I know they are just parroting something they don't understand.

Bitcoin uses cryptography to create digital currency. It is a cryptocurrency. Saying it's not is like saying air is not gas. Yes, many types of gas are toxic and dangerous.

When people say Bitcoin not crypto as their focus, it's like saying that for example a conference is about air and not the general category of gas. But that does not mean air is not a gas.

Bitcoin not crypto means that whoever says is focusing on this particular one, most of them think that other representatives of this category are junk, but this should not mean denying reality. Bitcoin is a cryptocurrency. Pretty good one, maybe even the best one. But a cryptocurrency.
