You don't technically need to enter the "university in the field of gaming." There are many opportunities in the world of 3d modeling. You need to know where to look, and to have a plan of action.
Here's some tips to get you started:
1) Network! Make connections in social networks such as Linkedin to gain contacts. These contacts are a source of job opportunities.
2) Don't limit yourself to one platform. Join a few specific websites that post and discuss work related to your field/interests.
3) Broaden your horizon. Don't think you need to limit yourself to "gaming" or "architecture" jobs. After looking at your work, you could use your skills to make 3d furniture for department stores looking to advertise their latest products. Gaming tech and 3d architecture modeling is used in various industries.
Hope my words bring you wisdom.
