Throttle rate for CRUD APIs

I found in the Timestream documentation that "The maximum number of Create/Update/List/Describe/Delete database/table API requests allowed per second per account, in the current region"

Does this mean that if I have a Lambda function that writes data points into Timestream. That function can only write 1 datapoint per second?
If YES, What if I have hundreds or thousands of devices that need to write data into Timestream ? For sure there will be more than 1 data point write per second.

thanks
