Qatar seems to me by far the worst team that participates in terms of quality? The players are used to playing football in the heat, other players from other countries have that less. They also have the home crowd behind it and will be hugely motivated as this is probably the only World Cup they will ever be allowed to compete in. In the group with the Netherlands and Senegal and Ecuador, there is still a group where you have chances. The Netherlands seems to me to be the winner of the group, Senegal is the 2nd best but Qatar has the advantage that they play the opening match against Ecuador, they could still win if things go well.
