The basic summary would be:

700c -> road bike size wheels
25mm -> width of tyre.

So 700c x 38 would be big tyres suitable for the sort of thing you
are proposing

Tyres labelled 26 x 1 1/4" etc are for old roadsters

Tyres laballed 26 x 1.25" are for MTBs. Note that these last two examples
are not the same size tyre even though 1 1/4 = 1.25!
