Texas has 4x the population of Washington state, has more urban centers and a much larger state. As a % of population, looks like WA has more migration compared to Texas given your numbers
Also, as others have pointed out, most of the TX influx has been in/around Austin, so it's not like people are moving from SF to the middle of nowhere in TX, and having no impact on the local communities. Real estate prices in Austin are skyrocketing, as would be expected, in the few areas where people are moving to.
