API Gateway throttling -- burst limit vs rate limit

I can't find any documentation on these two terms. I pored over AWS docs and Google results.

What is the difference between burst limit and rate limit? When I go to change the settings for default route throttling on my API, there are just two number inputs. It doesn't say what unit or time frame these numbers represent. Is it API calls per second? per minute?

The burst limit defines the number of requests your API can handle concurrently. The rate limit defines the number of allowed requests per second. This is an implementation of the Token bucket implementation.

The official documentation only mentions the algorithm briefly.
