I don't think it is. Usually, titles like this are part of fictional stories. But sometimes, they might incorporate some real-life elements and blend them with fiction to make the story more engaging.
Hard to say for sure. It could be inspired by real-life experiences but transformed and dramatized for entertainment purposes. Not everything presented might be 100% factual.
The significance might be in the idea of survival. It could be that someone has been through a lot, but they are still alive and kicking, and their story is a testament to human resilience.
