Prometheus gathers data by talking to exporters. It makes HTTP requests to gather metrics; the exporter accepts the HTTP request and returns its metrics in a simple format <https://prometheus.io/docs/instrumenting/exposition_formats/>.
There are some exporters released by the Prometheus project itself (e.g. node_exporter, windows_exporter, snmp_exporter, blackbox_exporter), and others released by third parties for gathering data from other sources. If you are trying to gather data from some system or service that doesn't already have an exporter, you could write your own <https://prometheus.io/docs/instrumenting/writing_exporters/> - or if it's an application, you could add an exporter to the application itself. "Clients" are the libraries which help you write exporters. You can find a list of known ones here <https://prometheus.io/docs/instrumenting/clientlibs/>.
