no,

an artstyle is something a person has. if you're a artist, then the thing that sets us aside from everyone is our artstyle and ocs.
like a example: a stickman would be a "artstyle" beginers would do. so that artstyle is common and people arent "coping" each other on the stickman artstyle.
example 2: this artstyle of mochi's no one else has on the app, since its not common, like how stickmans are very common in life now, and she made it up on her own (unless theyre trying to copy mochi)

now, mochi's artstyle couldve been used BEFORE her, but it wasnt on this app. so, this IS HER artstyle and it belongs to mochi. plus, animes will have different styles, like how mochi compared "Dragon Ball Z" and "Demon Slayer", they dont have the same style, you can tell the animes styles difference. are you gonna say my artstyle is in anime? no? i didnt think so.

summing it all up, this IS mochi's artstyle.

What anime looks like my style? Even in anime, different styles exist. Shading, highlights, the way eyes and hair tuffs are drawn, anatomy, and even small things like if they draw fingernails. I mean, since both Demon Slayer and Dragon Ball Z are anime, you're going to tell me they look the same?  ( ≖ଳ≖)
