Gimp is a raster (bitmap) editor and works in pixels. That boundary you see the edges of the pixels. The line shown by the ellipse tool does not really exist, only in the Gimp Interface.
Back to your screenshot, That is very-very small and is much magnified. I duplicated here. 17 x 21 pixels. and 2300% zoom Like this: https://i.imgur.com/pOCYyka.jpg
To make lines appear smooth anti-aliasing is used, so make sure that is enabled. You can fill a selection just by click-n-drag from the swatch into the selection or you can use the bucket fill tool or for something that small you could paint it in - up to you.
That gives this: https://i.imgur.com/fUVbbFj.jpg
Still looks jagged to you. Consider it in context with a more regular size canvas. https://i.imgur.com/kT72Wna.jpg
Want just a circle? Then use Edit -> Stroke selection like this : https://i.imgur.com/tcvieYb.jpg One proviso - use an odd number of pixels for the line width, otherwise you loose the anti-aliasing ( much like MS Paint https://i.imgur.com/FetcwSX.jpg
