It occurs to me there are probably people who think Lord of the Rings and Game of Thrones are the same thing.
Absolutely. If you're not into the genre, it all looks the same to you. Just like some people think that all westerns are just the same old "cowboys and Indians" cliches. Or can't tell the difference between a good slasher movie and a piece of junk.
Or, worse yet, think that all vampire stories are just rip-offs of Twilight
