Google Ads costs 17 TL for 4 clicks.

Yesterday, I experimented by running an ad on Google Ads. I had set it at 5 TL per day. Before the day ended, it reached 17 TL just with 444 impressions and 4 clicks. If the price is going up randomly, I don't see the point of setting a price limit. 17 TL for 444 impressions and 4 clicks seems excessive to me. Why is this cost increasing? Are certain keywords more valuable? I had advertised with the keyword "how to start a website." To make the ad effective, it needs to reach thousands or even millions of people. Probably, I need to pay around 5,000 for 1,000 clicks. I had a few trials back when it was called AdWords. It seems to optimize well when set manually and runs for a long time. It says it's constantly learning above; it seems like it really is learning. I am learning too.
