Quite simply, anyone can tell a story if they start at the beginning and go to the end. However, some people have trouble knowing where the beginning is and start before the beginning. Some people try to put in every detail of the backstory. Other people drop in things they forgot to mention and later need to tell to make something make sense or work.
The other important part is to know when to stop. When there is a group of listeners who become restless, then it is likely that it took too long to get to the point, or the storyteller kept going after it was finished.
But more than that, a writer has to engage the reader to care about the characters and what is coming next. Just because a person can tell a story, doesn't mean they can write a novel.
Make sure you write about people who other people can care about and put them in a setting that the reader can experience too.
Write well. Tell your best story.
