The ones with the "P" flags are prefail indicators that the controller manufacturer thinks will indicate failure. When value goes below threshold, it sets a SMART prefail status indicator that the host controller can poll. Unfortunately for SATA there is no way for SSD to interrupt the host controller to give such a warning so you need some kind of monitoring software to periodically poll the SMART status.

Your drive looks in good shape in my opinion but thinks can always change suddenly so always backup.
