As long as has_more is set to true there is more data available. You can get this data by increasing the page parameter in your request subsequently and running new request with that changed page parameter.
The next url for your example would then be
https://api.stackexchange.com/docs/users#page=2&pagesize=100&order=desc&sort=reputation&filter=default&site=stackoverflow&run=true
The other both properties quota_remaining and quota_max refer to the maximum amount of queries you may issue on that day to the API. In your example case you have used 46 request on that day and may do another 9954.
