I think that you are correct here. The Census outlines this here:

https://www.census.gov/programs-surveys/acs/guidance/estimates.html

It looks like the rule of thumb is that 1 year estimates are provided for
geographies which only have over 65,000 people. However, most tracts only
have around 4,000 people.
