As I recall, KML contains the latitude and longitude values for each location and/or point in a polygon that you can draw.
You'll need to extract this information FROM the KML file and then either present it directly to Tableau and/or use custom geocoding.
I don't consider myself a mapping guru, so others here may have better ideas.
When I directly use the coordinates with Tableau, it don't recognize them
as latitude and longitude. And for custom geocoding, I have to buy Tableau
Desktop, a software I can not afford it...

There are a variety of free sites that will do conversion to lat/long values, Elvis Has Left The Building put together a list awhile back:
Batch geocoder that Shawn recommends, for up to 1K addresses at a time:
In terms of Tableau not recognizing the lat/long values that you have, can you post your sample data here and/or post a link to your work in progress workbook on Tableau Public? That way users here can help identify what is going on.
As I recall, the points expressed in a KML file are not “ready to consume” lat / lon coordinates. I had to do some simple math (like multiplying the values by -1 or something) before they worked.
