It refer to stats you gain per level.

Didn't that matter unless you really want to know if its safe to bring the Servant when s/he didn't have max level, stats-wise, as their stats (by HP & ATK only, of course) may relevant enough to compete against enemies with higher level (of course its not 50+ levels kind of gap).

Scathach is Linear, that means she got same increase of HP & ATK value per level.

Gilgamesh is Reverse S, that means he got high increase of HP & ATK at beginning and end of Lv. 1 to Lv. 90. Making him powerful at early and end game, but need to catch up at mid game, stats-wise.

Waver is S, that means he got high stats by middle of Lv. 1 to Lv. 90 (the growth is based on their original level cap, not grailed level cap).

Among them, if you worry about stats due to slightly underleveled, regardless of their skills and class (maybe because of Bond, Event, etc), characters with S growth tend to be the best choice to fill the slots, as their growth happened in middle, allowing them to be fine holding their ground even against end game enemies in case something unexpected happened.
