I guess they mean that you didn't have to declare the type because you are handed a default size integer. This was at least the case of B, BCPL and very early pre-standard C.

Where have you read that? I ask because the same word can mean different things in different contexts, so knowing the context is necessary to know what "typeless" means. (Yes, some words are so ubiquitous nearly everyone agrees on their meaning. These words usually have their own wikipedia entry. "typeless" isn't such a word).

I have edited the title because "really exists" is quite hard to answer objectively. A simple search indicates that they exist, but it is not very clear what they are. Also, it would be useful to indicate the source where you read about these languages.

@meriton I think where I have read that is irrelevant and is an expose of personal data which I shouldn't do by principle. I thank you and Alexei for trying to help; I should try revise the question.
