You need to understand that you're asking questions for which there is
no specific answer.
I think Nick's first response to your question answered it best -
OpenBSD would be "better than anything else".
If you were to ask specific, detailed questions about specific attack
vectors, then specific answers may be possible, but there is no
generalized answer to these generalized questions.
I could answer that an attacker with a certain skill level, a certain
amount of time and certain other reasources available, would have a 20%
chance of breaking into a default OpenBSD install that is connected in
a certain manner.
Technically this answers your question, but in reality tells you
nothing, because the various 'certain's above are unquantified. If you
can quantify these for us, then a specific answer may be possible
(although I cant imagine for a moment that anybody would but the work
into calculating this for you).
Sorry that this isn't the answer you wanted.

Hi
This is clear and I truly agree, now maybe not everyone will be capable
of breaking into the default system openbsd (this was my first
question)
and evade from chroot (my second question) therefore the other way
around to ask about that concern would be which probability do you
estimate for even good hackers could break into the default, or evade
from the chroot.

That should answer your question.
