Meh, that doesn't convince me in the slightest. The game is full of inconsistencies like this. Check this out:
http://www.battle.net/scc/GS/damage.shtml It shows the sizes and damage types of the units, and both marines and zealots are size small (check out the chart). I have not seen any flavor text on the Protoss that marks them as size Large. When I do I'll consider changing the statistics
I'm very familiar with damage types, but they don't mean what you think they mean. (A Mutalisk is size Small, for instance.)
Why don't you look at the StarCraft: Ghost pics? There, the Protoss are again much bigger than the Terrans.
PS considering how weak-minded Zerg are, I think they should be a creature type called Alien Beast.
This is my interpretation of a Hydralisk. It is 17 feet 7 inches long, which comes out to Large since it curls up a bit in combat, and with upgrades it moves faster than a Terran civilian.
Hydralisk: CR 5; Large Alien Beast; HD 4d10+8, hp 30, Mas 15; Init +2, Spd 40 ft.; Def 18 (-1 size, +3 Dex, +6 natural); BAB +4, Grap +10; Atk needle spines +6 ranged (2d6+2) or 2 needle spines +4 ranged (3d6+2) or 2 claws +5 melee (1d6+2); S/R 10 ft./5 ft.; SA needle spines; SQ burrow, fast healing 3, sensitivity to psionics, Zerg traits; AL Zerg Swarm, Brood; SV Fort +6, Ref +6, Will +0; AP 0, Rep +0; Str 15, Dex 16, Con 15, Int *, Wis 9, Cha 8.
Skills: Hide -1 (+9 burrowed), Listen +2, Spot +3.
Feats: Point Blank Shot, Precise Shot.
* According to StarCraft: Revelations, it's measurably smarter than a Zergling.
