Logical issue in 'Outer join', why out join is not working, the way it should?

I am using outer join, I have two tables tblaccount with 33 records and tblcustchannelacct with 146 records, and I am writing a query to have only tblaccounts matching records with tblcustchannelacct, so only 33 records should come, but no matter how much I change the query I get 146 records.

Queries are below:

*-Select tab1.ACCOUNT_ID, tab2.ACCOUNT_ID

from tblaccount tab1, tblcustchannelacct tab2

where tab1.account_id  (+) = tab2.account_id;

Here I used (+) in the WHERE clause for tblaccount to include all the rows that is tblaccount but 146 i.e.: tblcustchannelacct no. of records are showing.

Now I used outer join with keyword of 'outer join' instead of (+)

*-Select tab1.ACCOUNT_ID, tab2.ACCOUNT_ID

from tblcustchannelacct tab2

left join tblaccount tab1

on tab1.ACCOUNT_ID= tab2.ACCOUNT_ID

LEFT JOIN keyword returns all rows from the left table tblaccount, even if there are no matches in the right table tblcustchannelacct.

(but showing the same 146 records of tblcustchannelacct).
