sys.dm_db_stats_properties seems to be misbehaving for a small table - how to get the number of records of a table in a different way?
Looking for row counts in stats objects is problematic.  Especially since stats are not updated automatically every time a row is inserted, deleted, or modified.

Use sys.dm_db_partition_stats instead.  It returns row count information for every partition in the database.

SELECT Name = QUOTENAME(sch.name) + N'.' + QUOTENAME(o.name)
    , dbps.partition_number
    , dbps.row_count
    , dbps.*
FROM sys.schemas sch
    INNER JOIN sys.objects o ON sch.schema_id = o.schema_id
    INNER JOIN sys.dm_db_partition_stats dbps ON o.object_id = dbps.object_id
WHERE o.is_ms_shipped = 0
    AND (dbps.index_id = 0 OR dbps.index_id = 1); --heap or clustered indexes only


I wrote a blog post on SQLServerScience.com that shows some of the problems with the stats properties DMV in relation to row counts.  That post uses this query to obtain row counts, and shows when the stats object was last updated:

SELECT Name = QUOTENAME(sch.name) + N'.' + QUOTENAME(o.name) + N'.' + QUOTENAME(s.name)
    , ddsp.stats_id
    , last_updated = CONVERT(datetime2(1), ddsp.last_updated)
    , ddsp.rows
    , mod_count = ddsp.modification_counter
    , ddsp.unfiltered_rows
FROM sys.schemas sch
    INNER JOIN sys.objects o ON sch.schema_id = o.schema_id
    INNER JOIN sys.stats s ON o.object_id = s.object_id
    OUTER APPLY sys.dm_db_stats_properties(s.object_id, s.stats_id) ddsp
WHERE o.is_ms_shipped = 0;
