WTF are Dimensions and Metrics in Data Studio?

Excerpted from the CIFL course on building dashboards with Google Sheets and Data Studio:
learn.codingis...
If you've ever worked with Google Analytics data, you're familiar with the differences between dimensions and metrics.
Dimensions are text fields, like Browser or City.
Metrics are numeric fields, like Users or Sessions.
You can slice metrics by dimensions - for example, slicing number of Users by Browser.
Data Studio uses this same concept, so each of the charts or tables you build will have both a dimension and a metric.
Date columns are a special type of dimension, formatted as a date, that can be used in time series charts and in date filters.

I hope you could help me, I have a database with the expenses of the employees with categories. I want to use the combo chart, the bar chart will have the expenses of a particular employee and the line chart will have the average of all the group by category.
I can't link the average with the filters. When I filter by Employee Name it gives me the AVG of the Employee no the AVG of ALL THE EMPLOYES IN THE COUNTRY.
I need to compare the Employee expenses with the AVG of the Country Employee
