When using a conversion tactic in google ads, will you only be charged for form submissions?

Question

Google Ads

I understand conversions in Google ADS. I used to do only default click-through ads. Understanding the example of the video, I understand that it is possible to set up ads so that money is charged only for the submitted form (which we set up through tags)? Those. When a user clicks on a site, money is not deducted from the advertising company? Or did I misunderstand something?
