Live betting question (mlb)

Home, draw, away.....(3:0) If you bet team A to win, but the 2 teams score the same amount if runs at the end of the game (7:4) - 4 runs each.. Why isn't that a push? I was told because you have an option to pick draw. Does this sound correct? Heritage....

It's pretty self explanatory. On a 3 way line, any draw is an automatic loss unless you bet draw. No pushes.
