Yep, so the point (I think) is to get you to contrast equality of opportunity vs equality of outcome. It's not hugely clear in the images, there are a few things that need to be assumed to make it clearer.
Firstly the goal is not 1 fruit, the goal is to have a many fruit as you need. For some reason these 2 kids both need a lot of fruit. Maybe they have huge seeds and 1 won't sustain a small child, I don't know.
Secondly, the tree in the first panel has fewer fruit to drop on one side, and it leans towards one person only. This is trying to communicate that they don't have equality of opportunity on a systemic level. Both children have 1 significant barrier (height), but 1 child has an additional barrier of fewer fruit possible, and their height barrier is twice as tall. There is also an invisible forcefield preventing movement of children from one side of the tree to the other.
So in the first panel, yes it is unequal because one kid gets nothing and the other gets something, which is an inequality of outcome. The difference in tree lean and number of fruit provides an inequality of opportunity - which is often harder to see in real life too.
The second panel asks the question "what if we gave them equal assistance?" by providing equal ladders. Which is great, but if the assistance provided is only enough to help one child overcome the problem they both face while ignoring the other 2 problems the other child faces, you won't have equality of outcome. And it can even cause greater inequality of outcome, because the left kid can reach a dozen fruit but the right kid can still only reach a few. For magic forcefield reasons.
The third panel is different to the second, because they're no longer only being provided equal assistance. They're both being provided assistance equal to their needs, but the kid on the right still has fewer opportunities because there are fewer fruit. They have more equal possible outcomes, but it's still unlikely to be an equal outcome even though you're (sort of) helping one kid twice as much.
And in the last panel, for some reason trees that are straight provide equal quantities of fruit on both sides? Whatever, the point us that the underlying systemic inequity has been addressed and you have proper equality of opportunity and potential for equality of outcome.
Sorry about length, I hope that reply doesn't cause more confusion.
