useFirestoreConnect([
{
collection: 'words',
where: ['createdBy', '==', auth.uid],
limit:10,
}
])

Not sure what you are asking here - the query you provided should work to load 10 documents from the words collection. Are you looking for that to be a random 10 or are you saying this query doesn't work?

Yes, my question is how to get 10 random documents from a collection?

Since that is not something directly supported by the Firebase API as a method, it isn't a feature here either.

For something like this it may be more advantageous to go with a Cloud Function that generates a random list of words by querying all the words and selecting a random set (maybe using javascripts Math.random). That could then be returned to the client. This can be especially helpful if you are hoping to only return certain data to the client from the documents since you can pluck that data off in your cloud function as well.
