Yes, but Unity targeted the Indie market with "free for small unsuccessful projects and we take a small cut of sales if it takes off" first and then Unreal jumped into that market. While Unreal entered that market from the opposite direction (offering a proper, supported high-end gaming engine to replace in-house engines of AAA gaming companies) they both converged into the same market when it came to selling to small players.
