You actually proved my point in the first line of your "Space Opera" quote..

is a work set in a far future space faring civilization

Isn't Star Wars, as you said yourself before your quote, set " A LONG TIME AGO....."

Ok, other than that, read the rest of what it says.....

Stop nitpicking, star wars has all of the other space opera science fiction elements......

Fantasy is usually medieval/ancient

Science fiction is usually set during/in futuristic settings

But there are exceptions, such as futuristic fantasy stories, or ancient science fiction stories.......

What if I write a story about time travel to the past??? Science fiction or fantasy???
