First, South Africa beat South Korea 1-0 to snatch one of the top two places in their group, meaning South Korea - who have a better goal difference than Scotland - dropped to third.
After that, Ecuador produced an unexpected 2-1 victory over Germany to finish third in their group with four points and seal a spot in the last 32.
Sweden then held Japan to a 1-1 draw, also qualifying from third place with four points.
Scotland were down to an 6.89% chance of qualification after that, according to Opta, but are now down to 5.49% after Paraguay played out a stalemate with Australia which suited both sides.
Those results leave Scotland sitting eighth out of the 12 current third-placed sides and on the brink of missing out on a knockout spot.
If teams in the third-place standings finish level on points, the rankings are then decided by goal difference.
That means Scotland will need to hope that at least four third-placed teams do not manage to reach three points, or they do so with a worse goal difference than them.
As it stands, there are four teams ranked below Scotland who have only played two matches, while there are two others who are level on points with a game to play.
