How do websites detect the use of "click", "type", and "sendKeys" commands?

I use UI.Vision macro using “click”, “type”, and “sendKeys” commands for data entry on the website.
After reading the official documentation and some topics on the forum site, I thought that using these commands could cause the website to detect using UI.Vision RPA (or not operating manually) .
Could you please tell me how the website detects their use?

I don’t think they can be detected these commands - unless you are clicking too fast. No human can fill out 10 text boxes in one second - that is how websites detect the use of automation tools.
