Stockfish’s value calculations are grounded in the likelihood of it winning from that position when playing itself.
Pedantically, it’s grounded in the likelihood of LeelaZero wining from that position when playing itself. Stockfish NNUE is trained on LZ data.
Previously they were completely human-crafted, grounded on repeated empirical testing of Stockfish and picking what works better. I suppose they’re still grounded in the latter.
