That seems like a very cherrypicked number. Yesh Din have an updating report on the years 2005-2022. Haaretz focuses on 2017-2021 for some reason. Within those years, anyone can pick any specific time with either a dip or a peak in statistics and surely these would paint very different pictures.
This is the Yesh Din website:
www.yesh-din.org
In it, the following report is highlighted:
Yesh Din write that they followed 1,531 cases, in which 7% ended in conviction. However they only participated in 91 cases, of which 50% ended in partial or full conviction.
Don't worry about the Hebrew, I'll translate.

(Yesh Din legal case results between 2005-2022, 91 completed legal processes, 13% full conviction, 13% conviction with plea bargain, 24% partial conviction, 22% guilt without conviction, 20% dropped criminal charges, 8% acquittal).
It is possible they prioritized cases in which they were confident they could succeed, which in turn could mean better evidence in those cases. This leads to the following data point. We can see that only 8% of cases were dropped because suspects were not found guilty. Vast majority is a lack of evidence.

Now let's see if there is any apparent bias here. Maybe Israel's police just doesn't like Palestinians and closes cases unjustly.
We can see from this snippet here that although cases of nationalistic crimes against non-Palestinians (9.5%) are more likely to end in conviction than the same for Palestinian victims (2.6% - Police, 2.4% - Yesh Din), those are still low numbers that tell us more about the process of investigation rather than any biases.

We see another kid holding what is likely an explosive device. Both kids seem to have been hit at the same time and it is possible the bullet may have pierced one and hit the other. The trajectory and direction they were looking at seems to support it.
I think at this point, this war and the many events around it, have shown us that things usually aren't as they first appear.
