I started a couple years before you. Youll be fine, pick the right gym. I started in Muay Thai, Boxing, BJJ, Krav Maga. I love it all. I think a good “real” physical is most important. Be really careful with sparring. I used to spar much more regularly. I think if both parties are mature and careful youll be ok. A lot to be gained from the timing distance experience you get from sparring.
Good luck, I say go for it.
