Of course you can! You first get rated prior to any flying done in the aircraft. There's no way you get your type rating afterwards.
A reason why one would be type rated without hours could be:
1) Company went bankrupt after the sim training;
2) Massive layoff during covid
3) Self-sponsored type rating
4) Lack of planning from crew control, so once you've finished your type rating, the fleet manager sends you back to previous fleet or bumps you to another one lacking of pilots.
