Normally, I'd agree. But, I feel I need to add two provisions on this statement, at least in terms of jumping.
1. The horse must be sound. Some horses should not be jumping at any height due to health reasons.
2. The horse must be a reasonably safe jumper. Some horses are disasters on four legs the minute you ask them to jump something. These horses need to find a different career.
As for the OP, I see no glaring conformational flaws that would prevent her from jumping. However, I would need to see some good confo pics of her legs in order to let you know for certain. Biggest thing if you have any concerns re: soundness would be to talk to your vet.
Additionally, I recommend getting help for a trainer. Jumping can become very scary very fast when you don't know what you're doing. In order for both you and your horse to have good, safe experiences, I'd get some experienced help.
Good luck, have fun and stay safe!
