Indeed, as others have mentioned, you get 60k queries for free! Don't even need to add a card. Then, you rather pay for the usage (primarily by number of queries) you have. The $49 Pro plan you mentioned gives you additional features, such as more projects, higher query limits, and a lower $$ price per million queries. On the Starter plan though, you can get going for absolutely free, incl. those 60k queries, and only pay for the queries above that.

We are also working on making this simpler to understand. We want to make sure our pricing is as easy to grok and as affordable as possible. Keep an eye out for improvements as we get to GA!
