Confused

Ive had credit problems in past. I paid $100.00 a month for attorneys to help me straighten my credit out. Pay $60 a month for Myfico, have credit karma and score sense and they are all different scores. How can that be?? How are the same agencies have different scores??? Help me understand!!!! Theyre all different. Trying for mortgage and was going by my fico score and they told my that my score was -60 below what I thought it was. How is that???
