I'm a bit of an animal nut so here goes:
Lions your odds are not great. You must have seen how domestic cats something "play" with their "food" (mice, rats, etc). Eventually they get bored of it and go off and do something else. Lions and lionesses will only go for you if they are hungry and need to feed. Most of the time they are bored and just find things to amuse themselves.
Ok. Now Hippos. Very very high chance. The animal that kills the most people in Africa isn't lions, crocodiles, venomous creatures…. It's hippos. They don't mess around and will obliterate you even if you aren't food. Watch a video of how little pressure it takes them to crush a watermelon.
I'm not a betting person but the odds are way higher with a hippo.
Edit: ultimately humans are dumb pieces of shit and we'll all wipe each other out eventually. Birds are the evolutionary masters along with sharks rather than us stupid apes. They'll be here once we are long gone.
