The numbers are the same. The +100% is to determine the chance TO HIT. Not to resist.
I think that video only made things more confusing than they really are.
There is no +100% nor a "chance to hit" based on potency. There are:
1) The chance for the ability to trigger (e.g. Palatine's stun is 70%, for some it's 100%). This has nothing to do with potency, and contrary to intuition and what many people think, increasing potency will not improve anything here;
2) If the ability did trigger, it can still be resisted: tenacity check (tenacity minus potency, minimum 15%). If resisted, it will print "resisted" on the screen. If it happens a lot to you (e.g. against Raid bosses), increase potency may make things better (e.g. Rey against Nihilus has a chance to be resisted less with potency modding; counter-example is Traya and her Sabers have such high tenacity that you can't overcome it).
A character needs to have really high tenacity (more than 80%, probably even 100-120%) for it to resist abilities at a significant rate, since most ability-dealers have high natural potency and/or boosts.
