But that is about the ISP (and all hops in between). The provider, where you buy the domain, does not see the traffic at all. Basically the domain seller just controls the nameservers for that domain, but doesn’t see the traffic that goes to those domains.
Basically by buying a domain you buy an entry into the telephone book
You can rent a cheap VServer as well and use its static IP to forward traffic. Easiest for it would be SSH reverse tunnel. Or you could VPN it with your homelab (connection established from within your homelab).
If you don’t want to rely on an external service you could as well establish a VPN server within your homelab and use IPv6 to connect to it, although the disadvantage would be, that if you’re trying to connect from IPv4 networks ‘outside’ that wouldn’t work.
Just listing some options to research. Welcome to the hobby, have fun 🤗

Or if you have one of those fancy new “bill by the minute according to exchange prices” contract in the EU, you might even receive money for using electricity at certain times 😅. But those times are (yet) far in between, so blasting the sweet free energy on crypto is not really viable.
How do I learn
…you say in your OP. Yet instead of learning, you complain “what kind of crap server is that”. You don’t learn by thinking anything is the softwares fault.
It is perfectly normal, that you can reach the server IN your home network only when you are connected TO your home network. That is a security feature by your router and thus by design. But in order to learn how to open it up, you would need to be willing to learn. About security, about networking, about how to find servers, i.e. the internet and more.
But for the beginning: how is that even bad or crap? Like, it saves your photos when you come home and connect to wifi. Awesome, congrats!
Balatro.
After I finished the first run, I was like “cool, now the number I need to beat is higher. So what?”. Which is strange, because I love deck builders, I like beating higher numbers like e.g. Brotato. But for some reason I could not be bothered with Balatro ¯\_(ツ)_/¯
You put them in a safe. Safe falls down, spinning is gone.
You put them in a safe and forget about them for some time. Flash is gone, spinning still has data.
Don’t even need storage or performance or anything on the VPS, just forward stuff to the homeserver.
