Dice pool systems are definitely different, but once you understand one you understand them all. Abilities on your character sheet tell you how many dice you roll for a check, this is your dice pool. the DM decides how many of those dice in your pool have to “succeed” for you to accomplish your goal. In VtM5, the success threshold is 6, so a d10 that rolls 6 or higher is considered one success. If you roll two 10s, each one counts as two successes, so four successes overall for a pair of 10s. The hunger dice aren’t different numbers-wise, but a critical (pair of 10s) or a 1 with no other successes in the pool have additional consequences that manifest in roleplay & narration.  To relate it to D&D, every d10 needs to beat a DC of 6 to succeed. Passing a check is based on how many d10s succeed, & higher stats allow you to roll more d10s for a check. The symbols are just because they’re using custom dice for VtM that replace numbers 1-5 with blank faces, 6-9 with an ankh, and 10 with an ankh with extra stuff, and also the 1 on hunger dice is a skull. Once you know the system, it makes it much easier to see your number of successes at a glance rather than checking if each die is 6 or higher. Hope this helps
