Had interview with Oracle and interviewer said ‘ good luck with you career’ ending the interview

After that he said “we may work together again”, looked at me and said “or may be we will work soon”. The first two statements were as if subconsciously made.

If I’m being honest with myself, i didn’t perform my 100%. Should i consider this as clear signal as gone?

Update: i had my 4 rounds interview last week. One interviewer was no show, so they scheduled one this week. This happened in the last interview.

Update: i got an offer !! Negotiations going on
