Questions about this teapot!

Hey guys, complete newbie here! My friend just gave me a teapot and some other tea related accessories, but I just wanted to ask if this pot is good enough to start?

I was a little interested in getting started on a tea journey but I noticed that this tea pot (Kyusu?) has a little steel basket infuser that I can pull out rather than the usual mesh that I saw online. From what I’ve read, the basket kind of limits the volume of how much the tea can spread out but I don’t really know if it’s honestly that impactful for brewing since I’m new here.

Is it okay to start with this and then eventually look to upgrade? Can I just ride this thing out for now? Oh also if this tea pot is good enough, is it too big if I’m just kind of brewing tea for one person? I keep seeing a lot of smaller vessels since I’m assuming that people are only making 1-2 cups.

Thanks guys for all the help!
