How to interpret Websocket API Connection Minutes Pricing

https://aws.amazon.com/api-gateway/pricing/

It is said:

$0.25 per million connection minutes

So if you have 1million users that all are connected to the websocket api, then it would cost 0.25$ per minute.

And if you have only 10 users that all are connected to the websocket api, then it would cost $(0.25*10)/1,000,000 per minute.

So basically, the formula is:

$(0.25*x)/1,000,000 , where x is the number of active users

Correct?
