Help a new affiliate marketer…

I am interested in affiliate programs, i found it very interesting. so my question is about the essential keyword i will use, i spent some hours to find a good keyword, google search gives me 200.000 result for a special keyword and +150 % in progression also keywords tool gives me 33.000 monthly searchs with a small competition. Do you think it’s good to start with ?
Thank you
