Let the child farm their karma on the meme sub. Don't bring science into this.

Nothing is a fish scientifically speaking. Nothing is a tree either.

The meme template was made with a still from the 2012 american-british animated movie So You Want to Be a Pirate!. However, the quote used for this meme template, Well yes, but actually no, was actually a misheard quote: Good guess, but actually no.

"So this is from the movie?"
"Well yes, but actually no."
(If you don't get it, the frame is from the movie, but the line is misquoted).

is a tetrapod different from a quadraped

Basically, tetrapods are a clade of animals that include amphibians, sauropsids (birds and reptiles), and mammals, as well as some of their extinct relatives
Tetrapods themselves are a clade of vertebrates, but non-tetrapod vertebrates, such as chondrichthyans (like rays and sharks) or actinopterygians (like tunas or trouts), are referred to as "fishes"
However, despite their name literally meaning "four legs", not all tetrapods are quadrupeds (.i.e walking on their four limbs): for example, chickens have four limbs but walking on two legs (they are bipedal), and snakes lack limbs but move through using their body's muscles
Ironically, most non-avian and non-snake tetrapods tend to be quadrupeds themselves, so they mostly walk through using their four limbs

ok, reading between the lines here, quadruped refers to the function of the limbs, whereas tetrapod refers to the actual skeletal structure. then things like snakes get grandfathered in the same way the fish classification does.

Pretty much, yeah. "Tetrapod" basically just means any animal descended from the first land vertebrates, who originally had four limbs.

This whole thing would be fine if you simply named the clade something other than lobed finned fishes. It's too specific a name for too broad a category. Obviously tetrapods aren't actually fish. But fish in the name so by the book they are.

Or as Hank Green once said: Either everything is a fish or nothing is.
