Zero Trust Pricing Question - Gateways

The pricing for over 50 users is $7 but does that include gateways? One one page it appears so and in another it doesn’t. Also when you look at just gateway pricing it determines a user as 5000 requests.

How would I calculate that because just looking at 1 office on the free plan that has 4 employees they have 43K queries in just 24 hours. Something doesn’t seem right.
