This is 100% correct. Muscles that aren't used in your mouth/articulators (because your native language doesn't require them) atrophy over time. It is possible to strengthen these muscles with isolated practice -- on BoldVoice we have coach videos where they give you "reps" of muscle movements (such as 20 tongue-ups). We call it "a gym for your mouth" :D It's hard work, but it's the best way to get results.
