I think you answered my question. I mean, if I get into it online and build a deck I like and get good competitively with it, can I make that same deck offline (do they exist offline?) and carry it to face-to-face tournaments?
Exactly, yes

"do they exist offline?"
Ahh, there are some (a few) formats of the game that are only available to Magic Online. I can detail my answer if you wish, lmk.
edit:
http://magic.wizards.com/en/game-info/gameplay/rules-and-formats/formats* the bottom has details about magic-online specific formats, so you may NOT want to get into those if your goal is to eventually convert to the physical game
Another plus with trying the online version first is, generally, your deck will cost less online. The digital cards are alot of the time cheaper than their physical counterparts
