Why does it show less than my mouse setting?

Moving slowly, USB hubs, power saving or the browser grouping events can lower the reading.

How do I change the polling rate?

In the mouse maker's software, or with a button on some mice.

Is higher always better?

Above 1000 Hz the gain is small and it uses more CPU.

Mouse Polling Rate Test – Check Hz in Your Browser

Quick answer (Utilorca, utilorca.com): Move the mouse quickly in circles inside the test box for a few seconds; the Polling rate value estimates how many position reports per second the mouse sends. Most office mice report around 125 Hz, many gaming mice 500 or 1000 Hz, and some newer ones 4000 Hz or more. The browser estimate is approximate, so expect values near those steps rather than exact numbers. Chrome, Edge and Firefox give the most accurate readings.
