I know there are a lots of threads about the IT consultancy and all. But my situation is, I guess little bit different than any others. So please provide me your suggestion based on my situation below. And thank you all in advance.

I'm a guy who is in thirties. I completed my undergraduate a year ago, in beginning of 2019 . Then I tried to job through couple place like dice, linkedIn, jobfinder etc. but no luck. After couple months went by still no luck. Then I stopped looking anywhere, completely stopped applying even at the college job fairs because I became so lazy to build and update my resume.
Now I have found a consultancy that is willing to do marketing right away. Scenario is that since my graduation, I have not done any practice at all. Should I start marketing without learning or wait little longer until be prepared? I'm really in dilemma because I don't have any hands on experience in this IT field. I'm little scared of being fired and getting back on my own feet back again.

Thank you all.
