0 and 1 are ints: py> type(0) <class 'int'> py> type(1) <class 'int'> just like 2, 3, 4, -1, -999, 1098765432 etc. But just like 1 == 1.0 (a float), and 0 == 0.0 (a float), and in fact 1 also equals Fraction(1, 1) and Decimal(1) and 1+0j (complex number), so 1 also equals the bool True and 0 equals the bool False. The reason for this is that in many programming languages, there are no boolean values. People use 0 for false and 1 (or sometimes -1) for true. In the early days, Python was the same.
