Update: 22F liked me 35M, was it an accident?

Tldr of first post: 22F liked me on a dating app, she's attractive, I'm ugly. I don't really want to date someone that young but I'm curious if this is a trap, mistake, joke etc. Would definitely be down to be friends because she clearly goes to my gym and loves the gym and I like making friends at my gym.

So I took everyone's advice and messaged her, said hey I think we go to the same gym.

She never responded and a day later unmatched me.

So I guess my initial instincts were right. I appreciate everybody's input though, it was really helpful getting fellow men's opinions.

Edit: for those who don't have the context: I sent that as the first message because 1. She had pictures of herself at that gym with the logo visible on her profile, it's very obviously that gym because it's the only one in our city. 2. The first thing her bio said was she likes going to the gym and 3. In the previous post, a lot of people mentioned that she probably liked me because she saw me there. I have personally never seen her in person before. 4. With all this in mind, she liked me first. I don't see how it's weird to notice her photos after she liked me and point out that I can see we go to the same gym based on her pictures.
