Sounds like a scam.

Please provide a URL (http://...) for the website that describes the
strategy or offers the product.

Also, please provide a URL (http://...) for the particular lottery.

No. For example, there are 6525 ways (tickets) of matching exactly 4 out of
6 numbers drawn. That translates into about a 1 in 298.5 chance of matching
exactly 4, since there are 1,947,792 possible drawings (tickets) of 6 out of
36 numbers.

I still do not understand where 320 comes from. That is why I would like
the URLs that I requested above. They probably don't explain the math
directly. But they might have information that I can use to intuit the
computation.

For now, I stand by my finding that you would have to buy 2240 tickets in
order to be sure to match at least 4 of 6.

Of course, that makes sense to do only if the payout for matching exactly 4
is more than $2240, assuming $1 per ticket. (And of course, by "$", I mean
whatever your currency is.)

I suspect you will find that the payout is much smaller. Otherwise,
everyone would be doing this.

Is this how you first understood my question

Yes. You can download the file "uniq 4 from 6 of 36.xls" from
https://www.box.com/s/2a361ad6de78e8f4865e.

Columns A and B are somewhat configurable by changing A1, A2 and A3.
However, the table starting at A11 might need to be adjusted manually.

The macro that generates the results in columns D through I is hardwired for
the particular parameters that you mentioned, namely: drawing 6 of 36
numbers, and generating all combinations with unique sets of 4 numbers.

I hardwired the numbers in order to ensure the best performance.

The worksheet and macro might not be very self-explanatory. Let me know if
you have any questions or comments.
