Yes, there's even more unorthodoxy in Ronnie's cue action than explained in the video. People often say that Jack Lisowski is similar, and I can see some similarity in stance and physique, but not so much in terms of delivery, particularly the unusual elbow drop. Lisowski does steer around the ball a bit like Trump, although not so pronounced.
A player who reminds me of Ronnie's elbow movements is the Chinese prodigy Jiang Jun, who won the World U18 in 2019, aged 13. But he's still developing and might well make some technical changes as he grows.
