It could be both. With wet layup if you are not experienced or very careful, it is easy to use too much resin. That in itself will cause the laminate to be thicker and full of excess resin. Also some fabrics will compress under vacuum and often this is quoted as the consolidated thickness so its worth trying to find out if your fabrics thickness is based on that, or measured by yourselves.
Good laminators can get better consistency on thickness but also vacuum can help, be it conventional vacuum bagging of a wet lay up or more advanced techniques like infusion.
