If you want to know how they try to balance out the game, the makers often look at the win lose percentages for each race matchup
“One of the many tools that are used to assess balance in StarCraft II are the relative win rates for each race versus the others. However, if the matchmaking system is working properly, then a player of any race should be so well matched versus their opponents that their win/loss ratio should be very close to 50%, even if the races weren’t particularly well balanced. In effect, the matchmaking system could be hiding balance issues — if we didn’t use an adjusted win percentage which takes the matchmaker’s effects into account.”
