You need a pretty rare collection of results to be eliminated after the second round out of three. The only option I'm aware of:

• You need to lose both games
• The team which plays in both other games (i.e. your last opponent) needs to win one game and tie the other.

Canada lost both games, Morocco vs Croatia was a tie, and Morocco defeated Belgium. That gives the Morocco 1+3 = 4 points, Croatia has 4 points as well (3 from the win against Canada). Canada can reach at most three points from winning the last game, so they won't be among the top two no matter what. Canada will be 3rd or 4th in its group of 4 and drop out.

Qatar has the same situation in their group, so they are eliminated as well.

Most eliminations happen in the third round, which will start in a few hours for the first group.
