With respect to the first, in the official they show more statistics and they can also become negative, expressing more resistance, but as they are shown here in the whoami we only see the critical resist section and then the chance of receiving a critical, which implies that if we have more like we are in the resistance section we have a greater probability of resisting receiving that critical or that's how I understood it because other elements that claim to reduce the probability of you receiving a critical increase this statistic and do not decrease it.
For example, the Fantasia Harmony level 2 buff says Received P/M critical rate -25% and what it does is increase that statistic just like what happens when you have a jewel with the argument all received critical rate -7% increases the value of P.critical chance / P.skill critical chance and M.critical chance, if it is as you say then all these things are wrong just like other skills like the storm screamer that in dark its elemental burst that says it increases the m.skill critical rate received and what it does is to reduce that stat.
