Is it true that certain diseases are systematically avoided by Christian faith healers when praying for healing? If so, why?

I took a screenshot from [this video](https://youtu.be/CaIrpN8Ga-g?t=151) , juxtaposing two lists of ailments. The left list includes conditions that Christian faith healers consistently never cure, while the right list features conditions they are more willing to pray for, with more frequent claims of healing. Or at least, that's what the video's author claims. Is there any truth to this, and if so, why?
