Nah, she still doing better than all who's not A+ star.
She has fallen a lot from her peak, sure. I'm not arguing with you about that.
What I disagree with you is you talking like nobody cares about her anymore when she still moves 200K+ albums in 1 week. Country albums are known for longevity not debuting power.
She didn't "have to" switch career, she's still gonna release new music in the future.
