Would I be good in a street fight?

If I learned Krav Maga, MMA, and Ninjutsu, would I be able to defend myself in a street fight well? These are martial arts I like and others I like have no schools around (like systema or combat jiu jitsu). MMA is taught with the Krav Maga in the two hour session and the NInjutsu school also teaches it, but separately. So would these be effective in a street fight, even against multiple attackers?
