Is there actually a limit for losing online? Do you mean what happens when all the points given (1000) to you reach zero? I don't know what happens. I am good driver but in mario kart 8 even the best driver finds some difficult roads to drive on, or finds some bananas that blocks your path, anyway, as Rin says, you need practice. the first thing I did when I got mk8 was crying hehehhe because I wanted it so much heheh, ok now let's be serious heeh, the first thing i did before going online mode was race with the 50 cc and 100cc so you start getting to know the circuits, otherwise you would be fried in no time.
