Is this motor locked up?

95 f150 5.0 was told it sat for 10-15 years and has 72k miles, previous owner said it turned over fine and ran rough but drove onto a trailer and the starter went bad, doesn’t turn over by key this is what happens when I jump the solenoid, using every bit of my Cummins electrical power. Looks like it try’s to turn over but seems frozen up?
