ELI5: Why are there so many personal injury lawyers? Is it that profitable of a business?

Because a lot of people sustain personal injuries. 

They all need representation.

In addition, it is much easier to get clients that way, because clients are not required to pay anything out of pocket. Most personal injury cases are handled on contingency basis making legal representation affordable even for poorest people.
