If I delete and leave a Group MMS (iPhone), can people still see my texts?

So I was in this group text with around 10 people and when two of the people and I started having a conversation, someone else in the group chat texted me and called me obnoxious. I really don't like insults and confrontation so I wanted to leave the group message because I didn't want any more angry messages.So, if I delete and leave a Group MMS, can the people still see my texts or will what I sent be deleted? I'm actually a bit embarrassed and upset, so I would really like an answer.

Everything you send is already out there (received). You can't take it back.
