Is Google free or paid?

I'm curious to know, could you clarify whether Google is a free service or does it come with a cost? On one hand, we often use Google to search for information and access various online tools without paying a fee. However, Google also offers paid services like Google Ads and Google Cloud Platform. So, is Google primarily a free service with some paid options, or is there a base fee associated with its usage? I'm eager to understand the financial aspect of this widely used platform.
