It could be yes and no, it is used informally.

It just means "good bye". As in "I will see you again" seperti "Sampai nanti." sometimes in English we just say "See ya" or "Catch" - these are all informal methods of saying "I will see you soon" Slang terms

thanks

Standing alone, it is not a particularly friendly form of goodbye, and does have a question mark. If they said 'see you soon' or 'see you later' or similar phrases there would be no doubt. Baldly put as 'see you' it has an air of dismissal. Sounds a little like 'see you (maybe, but I won't care much if I don't)'

I think that's right statement)
