No, as you can read the article,
Higher the value of Gini higher the homogeneity.
It is homogeneity that we want while splitting a node because higher the homogeneity(purity) at a split, easier it will be to make a decision to either go left(maybe class A) or to go right(maybe class B) from the node while making a decision.
If the homogeneity is less then the decision at that node would be ambiguous to make. This will hence be a bad split
Imagine you are at some node and you have to go either right or left but in both the options the probability of class A and class B are 50-50, it will be ambiguous. Ideally speaking, one should be higher of class A and other should have a higher probability of class B.
Hope this helps,
