Can I become good at MMA with only private sessions?

I used to take Muay Thai 4 times per week but now I started doing 3 times per week of Muay Thai with group and 3 times private MMA sessions with the coach. The problem is MMA is illegal in my country since the government said that cage fighting is inhumane and practicing its techniques is illegal so there's no MMA gyms in my country no more so I have no choice but to take private MMA lessons with my coach who used to be MMA coach back when it was legal. The question is, I can be good at MMA with only private sessions 3 times per week and 3 times per week of Muay Thai with group?
