Is it true that for braces to pull in the protruding front teeth, it
must be 'anchored' to somewhere (molars?) in order to exert force to
pull the incisors and canines in?
Do the molars also move forward as a result, just like a tug of war?
Say there's 5mm space on each side, I guess the front row won't be
able to move in and take up all that 5mm gap?

I read that adult teeth have more 'filaments' in the teeth, will it
have any effect on the treatment outcome?

You've got the general physics right--in order to exert a force on the
incisors, you've got to exert the force against something else, and
usually the first molars are used for anchorage. They are more resistant
to movement, but if there is a concern that they could move forward some
kind of extraoral appliance can be worn to resist this tendency.
