If it says previous experience then sure, apply. Just note that your experience is in taking a training course. You can also add any other experience you have had. For instance working on computers for 4 years, literate in all Microsoft excel applications etc.
If it says work experience then you can still apply, but training is not work experience. They are looking for time spent in that field. You can apply for any job. It is up to the hiring person to make the final decision. There may only be three applicants that apply for this role and none may have experience but you will have training on your side. Good luck.
