It is no longer possible for other clubs to take over Liverpool's position in the first ranking if we look at it logically. (unless something very big happens and it is beyond our control).
15 points gap
10 matches remaining
So, it is impossible for Liverpool to lose 5 matches or more than half of them in the future. It seems impossible.
Although, Liverpool's condition is currently slumping because they failed to qualify for the next round in the UEFA Champions League. [even though they are at the top of the UCL standings, they had to be eliminated by PSG who won the penalty shootouts.

I would say the most impossible thing that will stop Liverpool from becoming champions is that Arsenal are unable to consistently score points
Even if Liverpool loses a lot of points, Arsenal will still not gain enough points (for such a distance) to catch them. Besides, now that Liverpool is out of the Champions League, I don't see anything that could distract them from the Premier League.
