Question Unexpected results with keywords by adding words

[Sage Minds]

I just purchased the Tubebuddy pro version. Currently, I am trying out the keyword research tool and I have observed the following. When I search for "inspirational story", I see search results of 18.5M. However, when I add an extra word, the search results increase. So, if I change it to "inspirational story of". Why is that? Because "inspirational story of" also includes the words from "inspirational story". So, you would expect that the search result would decrease with the addition of an extra word, right?

See photos for the results.

I would love to hear your thoughts!

It is not shocking and not wrong. When you searching exact match keywords (inspirational story) it have limited searches so it have low search volume and when you search phrase match keywords (inspirational story of) it have hight number of searches. So its different in above both picture.
Result is right. Please Don't panic.
