I am trying to find data of rivers that are not made of simple lines. I need polygon data so that the river bed is visible.

Is there any global or regional data source?

    Yes, this is exactly what I was looking for, the rivers are real shapes not just lines. Are there more datasets like this for the whole world?

Whilst this is not polygon format, MERIT Hydro: Global Hydrography Datasets does provide a raster of river width and this is a global dataset. You can convert this into a polygon format.
