Can all participating teams in the 2022 FIFA World Cup Qatar 2022 form a collection?

The FIFA World Cup Qatar 2022 draw group stage has come to an end. I think everyone wants to know the specific situation and details of each grouping after understanding the grouping situation (brothers who have not yet understood the grouping can read my first article). This time, I will give you an overall analysis.

First of all, introduce the general rules of the World Cup draw:

All teams are divided into four grades, with eight teams in each grade. * * A-H is divided into eight groups, and each group is divided into four grades: A 1, A2, A3 and A4. First, draw lots from the first team in turn (i.e. 1 -2 -3 -4) to determine which group the team is in, and then draw lots for grouping order immediately after each team draws lots. Because it is stipulated that the first team must be in the first order in the group, the remaining 2, 3 and 4 teams should draw lots for grouping order, which is not allocated according to grade. Moreover, there is also the principle of avoiding the same continent, that is, two teams from the same continent cannot be in the same group, but because there are too many European teams in 13, there must be two European teams in the same group, so the European team is set not to have three teams in the same group.

Although Qatar was the host of this time, Lady Fortune didn't care about Qatar. Qatar ranks first in Group A, along with Ecuador, Senegal and the Netherlands. Qatar should have played the opening match against Ecuador, but somehow the Netherlands played Senegal instead. So Qatar gave up the opening match because it didn't want to lose to Ecuador again? This is unknown.
