20 percent certain, based on the evidence available
"In 2004 there were estimated to be less than 400 speakers of the Kartujarra language. There may be far fewer than that number now as most children of Kartujarra people speak Martu Wangka which combines elements of Manyjilyjarra and Kartujarra languages with influences from the Warnman, Nyiyaparli and Putijarra languages. As such, children of Kartujarra speakers may not speak an unaltered form of the language and may be unable to identify Kartujarra elements. In 2006, Kartujarra speakers identified only five people who could still speak a pure form of the language."
