сразу не заметил, там около этих надписей знаки вопроса есть, напротив каждого выбора, на них нажимаешь и видишь подсказку:
if you choose NON-GAMING as the purpose for the deposit, funds uploaded via visa or mastercard cannot be sent to gambling/casino/poker merchants
и соответственно:
if you choose GAMING as the purpose of deposit, funds uploaded via visa or mastercard can be used for any purpose including transactions to gambling/casino/poker merchants
