You're completely right.
"Group 2 was a particularly close group. With*Brazil,*Yugoslavia*and*Scotland*drawing all their games against each other, it was decided by the number of goals these three teams scored when defeating*Zaire. Yugoslavia hammered the African nation 9–0, equalling a finals record for the largest margin of victory. Brazil beat them 3–0. Scotland however only managed a 2–0 margin, and so were edged out of the tournament on goal difference. They were the only team that did not lose a game in the tournament as well as becoming the first ever country to be eliminated from a World Cup Finals without having lost a match.".
