Generally when people say "Prepare to lose a lot" Is one way to try to protect against somebody getting too frustrated and just abandoning the game, a better thing to say is after a good amount of matches you should have a better vocabulary.
Now the amount of games you lose might be related to the skill gap, for example if you think a Novice would rank up to Federer's level by losing to the man 1,000 times, I think you wasted their time but don't mind me I'm silly.
Best thing I can give a beginner is find a character you like, find some matches and some videos and try to piece it together. Some characters are better learning than others. Some may tell you "You should pick Ryu" Personally I tell those people I'd rather quit the game than pick up this guy who I have no interest in and may teach me bad things as opposed to who I play.
