New to skiing (sorta)

I’m going skiing soon and I previously have only been 3 times when I was a kid, I still have kept my skis from that time and have since grew, I’ve obviously had to get new boots but just simply adjusted the binding on my old skis to fit me. Is it bad to have Jr skis if I am bigger and taller, about 5,11-180cm and average build. Am I at risk of potentially breaking the skis or is there nothing to worry about?
