SQS Billing when triggering lambda

Question

SQS pricing page mentioned

Every Amazon SQS action counts as a request

SQS pricing strategy has some pricing buckets, like First 1 Million Requests/Month is Free, From 1 Million to 100 Billion Requests/Month for Standard Queue is $0.40, etc.

As per AWS doc, to trigger lambda from SQS, three SQS actions are required as given below.

1. sqs:ReceiveMessage
2. sqs:DeleteMessage and
3. sqs:GetQueueAttributes.

My questions are

1. For every lambda invocation (triggering) do all these three actions are execute?
2. If yes, do all these actions are treated as a request?

In that case, every trigger for each 64KB payload chunk consumes 3 requests. If this understanding is wrong then what is the request count calculation for every trigger execution?

Thanks in advance
