How to calculate the Grab Maps tile cost?

"Hello, I apologize for my poor English. I want to use the AWS location service, particularly to retrieve maps, and I noticed that they use OpenStreetMap. However, I'm still confused about the costs. I found information about tiles on the map like this.

https://docs.aws.amazon.com/location/latest/APIReference/API_GetMapTile.html

in the article they said "so a tile containing data for the entire world at (0/0/0) will be split into 4 tiles at zoom 1 (1/0/0, 1/0/1, 1/1/0, 1/1/1)."

I found information about zoom levels in this link.

https://wiki.openstreetmap.org/wiki/Zoom_levels

If I want zoom level 16, it means I will get 4,294,967,296 tiles. According to the information, tile costs are charged per 1,000 tiles, with a charge of $0.40 per 1,000 tiles. But based on the data provided by OpenStreetMap, if we use zoom level 16, there will be 4,294,967,296 tiles. Then I used the AWS calculator:

https://calculator.aws/#/addService/LocationService

and the result assuming 1,000 hits per month with zoom level 16 is: Map tiles retrieved (Vector or Raster): 4,294,967,296,000 per month * 1,000 multiplier = 4,294,967,296,000,000 per month Pricing calculations: 4,294,967,296,000,000 Map tiles retrieved per month x 0.00004 USD = 171,798,691.84 USD per month Map tile retrieval cost (monthly): 171,798,691.84 USD

In my opinion, there seems to be an error in the calculation, and this doesn't even account for users scrolling to view other positions. Can you please clarify how it should be? Thank you all..."
