I was once rebuked for saying that something was inevitable when it wasn't literally inevitable. It was something that prima facie would come to pass, unless something ruled it out. I've heard people using "inevitable" that way. I think we are talking about how future events have a pull to them that feels irresistible. But literally speaking, these events are resistible, at least, they might be for all we actually know in the moment, and we never literally meant to make the claim that they were truly not avoidable. I think there should be a term for this version of "inevitable". So, I propose "semi-inevitable".
