This, 100%.

Of course, to get a specialization you have to become an expert. No one is going to pay you for that. There are more ways in than just out of university, but they typically require a lot of additional work/effort.

A buddy of mine always wanted to make games. He's done it successfully... after several years working on "normal" software in Big Tech, he successfully transitioned to the games industry and is now a graphics engine expert. Victory! But it took a long time to get there: he had to learn a LOT in his spare time, and then it's been ~10 years of crappy underpaid jobs (with multiple layoffs!) for him to finally build up enough industry cred to where he can do the work he loves and get paid well for it.
