Anime don't necessarily follow IRL timeflow, but we know the timeline for F/SN and F/GO, as it was confirmed in the games. F/SN occured in 2004, while F/GO occured in 2015-2016 (2017-2018 in NA). You can see that in Solomon Singularity, where Roman confirming that we should clear Solomon before 12/31/2018, or we will die.

So I assume that F/GO base Rin, used as a vessel for Ishtar and Ereshkigal, is about 29-31, because she was 17 in 2004. I don't remember anything in game which mentions her vessel's physical age anyway.

As for Sakura, I think it's because Parvati is pure fanservice Servant for HF's promotion, she doesn't appear in any in-game story or event and her Trial Quest is just "well we randomly found her in Fuyuki".
