i cannot speak for gambit-tiger2 so far,
but i can guaranty you that for gambit-tiger1 in relation to rebel-tiger13
the success is on gambit-tigers side.

i think the explanation is easy !

gambit-tiger will lose a few games due to risky style.
but it will not lose as much games due to doing nothing as
rebel-tiger13 will do.

if you have 2 similar programs, and the one is more agressive,
the more aggressive will IMO make a better score over all.

if you have a strong chess program, that is not trying to get the initiative
or is doing almost nothing than waiting for opponent mistakes,
it will not be very strong.

the reason fritz and junior do get high scores in schweden is not because these
programs DO something. but because of book-learning effects and
outsearching the opponent.
but if they would have to play against itself, and ONE engine would be
a little more DOING something, the one that tries to get the initiative
would IMO win.
