Two matches with one loss and one draw clearly reduce their chances, so I think it's reasonable for bookmakers to give Atletico these odds because they have been a little worrying since the start.
Although this kind of performance seems somewhat normal for Atletico, as every year they start the season poorly and slowly build hope, winning the title is clearly very difficult.
In the end, we will only see competition until the end between Barcelona and Real Madrid, because every season is like this (except for the 2020 season), so I don't have high hopes for Atletico.
They have always been a top club in La Liga, which is undeniable, but making them a contender for the trophy seems very difficult because Simeone has always been monotonous every season and is only ever satisfied with a Champions League spot.
Atletico Madrid doesn't seem ready for the big games this season because how can they be missing out on good points when the season just kickoff? If Los Colchoneros are losing stands and points in this early phase of La Liga then I wonder what they will do when it's mid-season, how will they be able to cope? Games are played and elite teams have targets, they're not dropping any charge other than facing themselves with formidable stands and leaning on big winnings. Barcelona and Real Madrid are enchancing their performances for this season, definitely not the time to give excuses rather pushing for outstanding results.
