That is because you do not write much.
My first SSDs were from Intel and I have completely worn them out by writing their specified maximum writable amount of data, in a couple of years or so.
After that, I have been careful to always buy only SSDs with the maximum amount of writable data that exist on the market. I have not worn out others yet, but those that have been used for many years show in their SMART counters that a large fraction of the permissible amount of written data has been reached and not much has remained until their end of life.
I typically write many tens of GB per day.
