Realtime raytracing hooks into an existing multipass pipeline like this by replacing select traditional techniques. The easiest to replace are shadowmaps and AO. You can also make use of radiance (diffuse GI) and reflections with one or two bounces. Traditional techniques are currently faster and give better results for just about everything else. Also, you can only afford maybe 1-2 raytrace samples per pixel at the moment, even with RTX, so they make heavy use of AI denoising techniques.
