Limits on documents returned in a content relationship

It's my understanding that a graphql call will return a maximum of 20 documents. Does that limit also apply to the number of docs returned in a Content Relationship?

In this example from my api, what's the maximum number of speakers I can I expect to get back?

query ($uid: String!, $locale: String!) {
  event(uid: $uid, lang: $locale) {
    title
    body {
      ... on EventBodyList_of_speakers {
        type
        primary {
          speakers_heading
        }
        fields {
          speaker {
            ... on Speaker {
              name
              title
              speaker_country
              _meta {
                uid
              }
            }
          }
        }
      }
    }
  }
}

Hi Justin,

Thanks for contributing to the Prismic community.

I'm gathering some information about your query. In the meanwhile may I have your repository name (you can share it in a private message if necessary)?

Fares,
