Is the sony fe 400mm f 2 8 gm oss good for sports?

Yes, for serious sport it's a strong choice. A 400mm f/2.8 is a fast, stabilised, autofocusing prime, and that wide maximum aperture lets in a lot of light for fast action. It's a lens for pro-level sport, though, not for a first setup.

On full frame it gives you 400mm as marked. On APS-C it becomes roughly 600mm equivalent, which is useful for distant action. For sport, pair it with a fast-readout body such as the Sony a9 III or the Sony a1 II. If you want to save money, the Sony a6700 gives you that 600mm-equivalent reach on APS-C.

Because it's a fixed focal length, you'll have to move to change framing. If you shoot from the sideline and need flexibility, a zoom may suit you better. Have a look at my picks for wildlife and sport and the reach guide.
