This how I interpret it to be also.
Personally, I work with Brigid 
& the Morrigan 
They both are Celtic 
Goddesses. I read & meditated & learned about different ones.
As for figuring it out, it will come in time as you explore & learn about different things & associations, you’ll probably feel a pull toward a deity or pantheon. Only you will know when that happens. & even if takes a while or nothing feels like a connection… either is perfectly fine! 
You’ll know what works for you & will be able to figure out which path feels right for your practice.
