Comma Format count of values in Matrix
Best way would be to create a measure that does your count like:
MyCount = COUNT('Table'[Column])Then, you can highlight this measure and go to the Modeling tab in the ribbon and click the "," button to format it.

I realize this is an old post, but here's another option for anyone else who comes across this (this functionality was added after the original post).
You can select the visual and go to formatting options, then choose "Field Formatting" and select the field you want, then enter a value for decimal places and select apply to total. There is not an option for "thousands separator" specifically, but populating the decimal places will result in the comma appearing.
The formatting options for counts of text fields appear to have changed in more recent versions (Version: 2.124.1805.0 64-bit (December 2023)). For visualizations involving cards containing counts of text fields the functionality is similar to that showing in the parent comment, but slightly different. On the format visualization pane you can set the decimal places to zero and get commas in your displayed numbers under the callout value section.
Setting decimal places to zero results in commas appearing in count values
