Takes a smaller percentage

The subject is wealth, so does "takes a smaller percentage" in this case is to be part of the smaller percentage of the wealth? or they get smaller percentage of the wealth? I hope you understand my doubt

this is how it's divided up, according to this chart, alright. Now, I'm going to give you and all of you who are watching this another option. And this is, let's call this number B, the B option. And this is how we're going to divide up: this is the top 20% takes a smaller percentage, and the middle and the second 20% and so on
