Yes, it's generally true, esp. if you are more than 6 months or so in, or if you're heading to another firm. If you quit after a month to go and dig wells in sub-Saharan Africa, then they're not going to pursue it hard as a) you're not getting benefit and b) it's seen as just youthful foolishness to have made a mistake in your first career choiceIf you really want the job, take it and pay off the training. Long-term, being in the right career track will be worth it and if you don't move now, you'll always be wondering "what if". You could also ask your new employer to pay off the debt as a hiring condition, but to be honest the environment for bargaining is pretty poor and if you've already got the job offer it's a risk that they'll withdraw it if you try and change the T&Cs at this point.
