Bengal is a breed, tabby is a pattern description, has nothing to do with breed.
The correct word for a cat with "tiger" stripes is actually mackerel tabby. Classic tabby has matching markings on front and back legs and the stripes are in swirls (that often look like targets) on their bodies. Mackerel tabbies may or may not have matching markings on their legs, and their stripes are straight across their bodies. Often when the cat is in certain positions the solid stripes separate into spots that give the cat a mackerel look, which is where the term comes from.
Both Classic Tabby and Mackerel Tabby have stripes that form an M on their forehead.
Tabbies come in almost any breed.
Bengals can be challenging, so be sure to read as much as you can on them to know what to expect. Why is he so beat up? Was he abused? If he was just brought in, very little will be known about his nature, and if he's been abused, you may have a tough road ahead of you.
I am not trying to discourage you by any means, one of the most rewarding experiences in the world is winning the trust and love of an animal who has been abused or is unsocialized.
I hope he does get to come home with you and lives a long happy life in the loving forever home you will provide for him.
