all the best and all for the best

I've seen people mostly use the expression 'all the best' when wishing someone a good luck. I have always taken it to mean whatever you do, desire, dream of, struggle for, may the best of its kind happen to you. Recently it came to my notice that some people extend the phrase further by including the part, all the best and "all for the best". I see it doesn't carry the same kind of significance in meaning as comapred to the other part, the most common one. It is probably just a way to say, whatever happens to you, may happen for the best. How do you take it? Please let me know. Thanks.

Yes, you have the right idea about these two expressions.

Thanks, Clive.
