Could anyone help me to understand if the slave is up to date with master?

I know the running paraters are YES that means then the replication status is good. Also, the SECONDS_BEHIND_MASTER is between 0 to 1 sec. But I see there is a big difference between binlog numbers from master vs slave. How could i confirm if there is a lag or not? Please advise.
