"What is the difference between commas and spaces for two variables in brackets on the command line?"
The difference is clarity: space can easily be a mistake, commas make the intent clearer.
This is not just hypothetical, we regularly get questions on this thread caused by the OP adding extra spaces into their matrix construction. Using commas makes the intent clearer and the bug locations easier to identify.

Previous answer is obviously correct, but if you wanted to see documentation:

In particular:
"...blank spaces act as delimiters in horizontal concatenation. When defining row vectors, you can use spaces and commas interchangeably to separate element"
