Hardly, if you do something full time for nearly 3 years you should be expert at it, you may not be the best in the world, but that obviously is a different proposition, for that you need skilled instruction from someone who is already among the best in the world and likely some sort of "hand up", ie you have very fast reflexes or are unusually strong or have particularly deft hands. Do it right now and surprise yourself, start doing something you are awful at but want to be good at and see how long it takes you to improve.
