If "Table 'xxx' passed rowcount (number) and checksum validation" is displayed, the result of Validate is success,Publication and the data of subscription is synchronized.
If "Table 'xxx' might be out of synchronization. Rowcounts (actual:number1, expected number2). Checksum values (actual:number3,expected number4)" is displayed, the result of Validate is failure,Publication and the data of subscription is out of sync.
Here is the query that is being executed against each table in the database if you choose to compare actual count and the checksum:
SELECT count_big (*), sum (convert (numeric, binary_checksum (*) FROM WITH (TABLOCK HOLDLOCK))
