Because while chess vigorously trains your brain, so does playing solitaire, memory games, a history test, etc. Meanwhile, sports train non-mental abilities, such as strength, speed, endurance, and agility. Chess does not require that, as a piece of computer software the size of a potato chip can beat every human put together. Although some chess players train their bodies in order to train their minds, they aren't using their bodily strength in the game, only mental.
Why is chess not a sport

A sport must meet these 3 criteria:
1) It must have a competitive element, and your competitor(s) must be human
2) Luck cannot be central to the sport
3) There must be muscle group training (excluding mental training) that will directly help you play better

2) there must be no luck involved

#2 wrong
all sports is kinda luck-involved.
Chess has very little luck (less than "real" sports, anyway). For example: In baseball, if the wind is blowing out just right, people hit way more home runs.

Ok good point Q, I'll edit #2 to be, Luck cannot be a central component, as while that could happen, it's not an intended part of the game

why must the competitors be human, I'm just thinking about how in the future there could be robots that are super good at like, baseball, would that make baseball no longer a sport?

Luck is 100% in all Sports and Chess too because free Will does not exist in universe

why did u just quote him with out saying anything

I think some people don’t see chess as a sport because it lacks physical movement, even though it demands intense mental stamina and strategic endurance, just like any competitive discipline. That said, mental performance is often tied to physical health. I’ve seen noticeable improvements in my focus and clarity since I started taking fitness more seriously. If you're wondering if is madmuscles legit, I found this helpful review that breaks it down clearly. Staying active complements the demands of a brain-heavy game like chess.

Chess is a game but not a sport. Some can be both (soccer for example is a game and a sport IMO) but not all.

Physical exertion is often seen as a core component of sports. While chess requires intense mental stamina and can be physically draining over time (especially during long matches), it doesn't involve athleticism in the traditional sense—no running, jumping, or coordinated movement of the body. Because of that, people might classify it more as a game or a competitive activity rather than a sport.
