You should ask PT4 questions in the
PT4 Support Thread.
Here are the definitions of the HM3 stats, that are the same as PT4 though named slightly different. I highlighted the 2 from HM3 that should be the same as the 2 PT4 stats you are asking about.
The rake stat most players generally use is the 'Rake' (preferred currency) or 'Rake Game' (game currency) stat that shows how much you/they actually contributed themselves.
- 'Rake' = The amount of rake divided proportionally by how much each player contributed to the pot in preferred currency
- 'Rake Taken' = The total amount of rake taken from each pot regardless of who won it in preferred currency
- 'Rake Attributed' = How much rake you personally paid from pots that you won in preferred currency
- 'Rake Share' = The amount of rake divided by the number of players dealt in in preferred currency
