Is there any difference between the two sentences above?
There is no difference in meaning between have and have got, specially in your sentence.
The only difference between them is that have is used in formal written English (and of course in spoken English) and have got is used in spoken English.
I have got is typically British. It is rarely heard in AmE, except as the contraction "I've got".
As for the "must" sense: I have got to...[do something] becomes, in AmE, "I've got to", which comes out sounding like
Or, "I have to" [do something] which comes out as
To add to the comments above, to "get" something is to acquire it. The reason that I have has a roughly equivalent meaning to I have got (or often I've got or even I got) is because one may be presumed to have acquired something that one has.
The difference between the two can be significant in some circumstances, for example when got is used as an alternate form of gotten:
I have got sick.
I have gotten sick.
This means that I have become sick, and I have sick isn't correct at all. The second usage is currently more popular than the first, but they go back and forth regularly over time.
