To begin, let's analyze the Four of Pentacles card. This card represents a moment of stability but also of limitations. It symbolizes a time when finances are constantly on the balance sheet and large investments cannot be made. It also represents the inability to see opportunities and to trust one's luck. In this case, the card tells us that there is little likelihood that you will have the same level of luck as your mother in gambling games.
Now let's move on to the reversed Six of Cups card. This card represents a moment of confusion, in which emotions take over reason. It also symbolizes the failure to recognize an opportunity when it presents itself. However, it also suggests that there may be an element of luck in the mix. The sign is encouraging and suggests that you may have more luck than expected in gambling.
In conclusion, based on the two cards analyzed here, our answer is "No". The cards suggest that your mother has more skill than you in having luck in gambling. However, the reversed Six of Cups card also suggests that there is an element of luck in the mix that can help you achieve some success in this arena.
