Is it permissible to pay money to study computer programs, such as Microsoft and Oracle products, knowing that they are American and "Jewish" products, and part of this money goes to buying books from America, this being in the context of boycotting these products?

It is permissible to purchase American or Jewish goods that benefit Muslims and cannot be obtained from Islamic companies or countries, especially if they are programs and technologies from which various matters can benefit. Therefore, there is no harm in continuing one's studies and benefiting from the programs available at the Computer Institute, and specializing in database entry based on Oracle, with the intention of benefiting Muslims.
