Your drive looks in very good health to me.

The big numbers in the raw values for the Raw_Read_Error_Rate and Seek_Error_Rate are sector counts, not error counts. In fact your Seek_Error_Rate attribute has recorded 239 million seeks without error.

The normalised value of the Raw_Read_Error_Rate (52) doesn't look great, but is probably normal. I suspect that it is calculated in a counterintuitive way.

Here are two sets of results (52 and 63) that I found with a quick search:

FWIW, here is my attempt to make sense of the SMART values in recent Seagate models:
