From a visual point of view, a 3D model is a basic schematic representation visible through a set of objects, elements and properties that, once processed, will become a 3D image.
It may be an animation that is rendered in real time when it is running, or an animation that uses three-dimensional but has been previously rendered, therefore it is only a video.
Rendering is the process of generating an image from a 3D model. The 3D model should contain geometry, viewpoint, texture and lighting information. The image rendering result is a digital image (raster).
Is a render with the same characteristics, the only difference is that you can orbit at 360 degrees in all directions, giving the model a better perception of the environment.
