Transaction Control Language commands in SQL | Using Commit , Rollback, and Savepoint Commands | PT

Hello man,
god bless your efforts.
A have a general enquiry as a new sql learner.
When i apply INSERT, UPDATE, or DELETE statement inside sql management studio, is the commit statement applied implicitly as part of the three former commands. The reason that i want to
make sure that when these three commands being applied would take effect on the database directly and at same time for all users.
Thanks for assisting me with my enquiry.
