Battle Outcomes Explanation

need help here again,
as much as i look into the dicestats and battle outcome
i still dont get it
what confuses me , is 1 vs 1
what does this mean?
one dice versus one dice?
or is that if i attack with 3 troops 2 troops? and that shows it a s 1 vs1?
because i cant read this dicestats, i have the constant feeling, that something is wrong here
and another example
if i deploy in rd one 7 troops,
attack 10 troops vs 3 troops and i lose all
statistically i do have crap dice
now what is happening in the long run
are the dice evening out or not?
because if they even out, how can this be random?
random is if they dont even out
my opinion
