You can easily migrate your Blogger blog to the hosted WordPress.com. Now, note I did not say WordPress.org. WordPress.org must be self-hosted. That means you pay for monthly hosting.
Whereas, WordPress.com is hosted and you do not pay WordPress.com for hosting the site.
I always refer to WordPress.com as the homeless shelter. It is great for starting your sitess and getting a good feel for blogging. But at some point you will, hopefully, move to an apartment or a house. Thet would be WordPress.org.
But WordPress.com , like Blogger.com will give you instant internet presence. I am thankful for how that has helped me and others.
