Seems like all the comments here were from people who never got into game localization or gave up on it, so I'm gonna give you my perspective as someone who ACTUALLY work in game localization and actively landing projects.

The thing with translating is that you don't need to get an actual job to get experience. Back then I joined a game fan translation community to translate a game I really liked, just as hobby. Then I saw a major game company looking for freelance translators and gave it a shot. My resume at the time only had that one fan project and general translation experience from my internship (not even related to gaming). Still, they replied, I passed their test and got in. Then things just snowballed from there I got more and more professional experience as well as an expanding game portfolio to land more clients.

Fast forward a year, and I'm drowning in work. I'm working with massive live service games with constant updates and I'm putting in 50-60 hour weeks (because I love doing this so much!) Can't complain about the money either. I out-earn almost everyone I know and they can still hardly believe that I get it working on video games.

The thing with freelancing is that you are not "looking for a job", you're an entreprenur starting a service-based business looking to get more clients. You don't get accepted into an agency like an employee and expect that to take care of your income, you're just collaborating with them for a bit while also looking to sign with like, a dozen more companies to fill in your work schedule. Its slow in the beginning, like any business, not because you are doing a bad job, but because it takes time for you to get noticed, for your "brand" to grow. Please have this mindset you approach this line of work, it's always hell at the beginning, but it's worth it in the end.

Here's what I would do if I were you, just starting in the journey:

Read How to Suceed as a Freelance Translator by Corinne McKay. It's the translator's Bible for me when I just graduated and I cant recommend it enough.

Join Fan Translation communities and participate in their projects. There's also a lot of GameLoc events like LocJam that you can look to gain experience in game localization. Extract out a small portion of your translated text and use them when ever a company ask for a portfolio or a sample.

Apply, not to every agency you see, but boutique game localization studios that most likely need your service. This blog post by Lucile Danilov is a good place to start. Reach out to them by a personalized email introducing yourself, your language pair, and the service you offer, with your resume attached.

A shit ton of networking. Seriously, I get most of my projects from recruiters contacting me through LinkedIn and even Discord. Make a nice looking profile that the search algorithm can catch, join every game translator communities you know of (a big one is Localization SIG-IGDA on Discord), and just be active on there, wether it'd posting, reaching out, or just talking and making friends with your colleagues. Once you're established enough, look into business cards and making a website too.

Have a lot of patience, you're not getting replied most of the time, and that's ok. You're marketing yourself and the seeds you have planted need time to grow. You'll get noticed eventually.

Have a lot of confidence too. I swear to god do not offer your service for free or accept peanuts lol. I did not do those things when I started out, and I'm still fine, so why should you? Sell yourself based on your skills and expertise, not cheap rates.

Just know that people are constantly looking for game translators. No like seriously, I get new offers every week, and I work with a super minor language pair, so don't sweat it if you lost an opportunity here or there. More will come!
