Like, I hear all the time that you shouldn't open any ports on your networks fire wall for security reasons this and security reasons that. But what are the actual security implications/risks of forwarding a port for something like Jellyfin or a Minecraft server or something like that? Explain like im 16 (or something)

As others have said, if you don't fully understand the implications of opening a port, you shouldn't open a port. Use something like TailScale or ZeroTier. You'll still be able to access your services but you don't need to open any ports.
