Games do simulate subsurface scattering, it's been a staple since the PS4 generation. They currently fake it rather than brute forcing the light paths traveling inside the surface like offline renderers do, but it still works fairly well.
In offline rendering the sky is the limit when it comes to SSS quality, if you have enough compute to throw at it. It's essential for getting skin to look right.
