That's still like a hundred to one or even way worse. We can simply shove in (group reader doesn't like) until they are so full that they can't move any more and then pile on each individually and still have a few billion people preparing the lion BBQ for afterwards.
There is a game on Steam you may enjoy. The name eludes me this second, but you get to set a number of certain types of things to fight another of your choice. It has modding support and can be quite fun. I'll try to find the name and edit it here
I think you are either overestimating the number of lions or underestimating thr number of the other things. It is to some degree a pure numbers game and there are just not a lot of lions comparatively.
