How does a controller link to a poll group?
I have three PLCs connected to HMI as controllers named PLC1 PLC2 and PLC3
I set up 3 poll groups also named PLC1 PLC2 and PLC3
Each poll group has a different poll rate.

I setup my tags to be assigned to a poll group, eg

Status_1 has addr 00100 (in PLC1 column) and is assigned to poll group PLC1
Status_2 has addr 00100 (in PLC2 column) and is assigned to poll group PLC2
Status_3 has addr 00100 (in PLC3 column) and is assigned to poll group PLC3

Is this correct

Yes, that is correct. The poll group is assigned to a tag and you associate a controller address with that tag.
