Is Han Solo a good smuggler? (TFA Spoilers)

Han Solo says that he had to go back to smuggling because that's the only thing he was ever good at. What evidence do we have that he was good other than his own words? Yet multiple times we're shown evidence that he's a bad smuggler. He owes Jabba so much that there's a price on his head and only gets out of it because Jabba gets killed by his girlfriend. When we see him in TFA, he gets boarded by two gangs and would have been screwed again if not for Rey and Finn being there.

He seems like a pretty bad smuggler to me. If not for the Skywalkers, he'd have been dead and/or broke a long, long, long time ago instead of just a long, long time ago.
