It is true that European exploration led to dominance in the Atlantic and Indian Oceans and over the people in Africa and the Americas.
Great Britain became a strong empire. It's imperialistic and expansionistic ideas made it explore and conquer new territories. That is how they had the new colonies in the Americas such as Pennsylvania, Massachusetts, Virginia, the Carolinas, Maryland, Rhode Island or New York. Britain also colonized many territories in Africa, where raw materials and natural resources abound and served to increase the power of the English monarchy. They colonized Nigeria, Ghan. Cameroon, Kenya, Uganda, Sierra Leona, and Tanzania, among others. The English were so powerful they did reach Asian territories and colonized such as Australia and New Zeland.
